I have a problem with the denoiser, I need it but it's messing up final render. Everything seems right.   Then when denosier comen in.    Presets are default and this is the first time this happens,  image its 1920x1080 with 512 tiles at a 1080ti.  I have volumetric scatter at .1  I gave up. Final result:   That´s at 5048 samples, denoiser radius 1 and turned off volumetrics, it lasted a lot, about 1/2 hour but i'll leave like that, thank's for the comments.
Since the Denoise feature was added to Blender I only use the default setting with it and it really does the work. But sometimes the denoise is noticable on some of my renders. How can I overcome the blurred effect? Denoising for me is a big help because my system is quite aged.
I've played around in the past of the 2D Flash fan-made version of the popular Valve game Portal.  It has basically the exact same mechanics, but as a 2D side-view flash game.  Lately I've toyed around with creating a simplified flash version of some of my favorite franchises (such as Zelda, Mario, Splinter Cell, etc.).  Of course, nothing is "stopping" me from just using the same mechanics and just changing the name to something not copyrighted.  I have witnessed projects that have tried to directly port a 3D game into a 2D simplified version, with the exact same plot and puzzles (Ocarina of Time in 2D comes to mind), and I have seen them being shut down.  But I am not likely going to exactly duplicate any game...just borrow some of the source material and basic underlying mechanics.  For example, if I were to make a Zelda-influenced fan game, I would have items such as the Hookshot, Boomerang, and all other sorts of ones from the Gameboy Zeldas; just with a custom plot and dungeons.  With likely the same mechanics.  What are the legal issues involved in this?  I used to think it was a "Don't do this ever; it's a bad idea."  But then I've seen the Portal clone, and now I'm curious. ALTER table - adding AUTOINCREMENT in MySQL Can we model gravitation as a repulsive force? This question is actually related to my earlier question ("").  The fact that objects move a lot in the universe and that the universe is expanding, can imply that gravity is a repulsive force that increases with distance.. so the farthest objects repel us more.  This can still explain several existing observations, e.g., why does the apple fall?   Motion is the result of such repulsion. Two objects unlucky enough not to be moving relative to each other get squished due to the repulsion of the rest of the universe  around them. The earth repels the apple less than the stars so it is pushed towards the earth.   Furthermore, it can explain the expanding universe without the need for dark energy.  This could be demonstrated in a thought experiment. If we take a lot of same-charge particles (with small mass) such as electrons and lock them in a large box at a low enough temperature. The mutual repulsion of the particles may cause similar motion as if due to gravitational attraction.   Another experiment would be to measure the slight changes in our weight during day and night when the sun and earth align (if their masses are large enough to detect the feeble change in repulsion).   [EDIT: the question in the original form may not have been clear. It is "can we model".. with a yes/no answer and why (not). If downvoting, please justify.

I'm from Sri Lanka. Yesterday I cancelled the appointment, I changed my mind. I will not go to the visa appointment. Now my question is how I get my refund? How can I force a program to open in a specific desktop? I've created an environment where I use 3 different desktop configurations, but every time I reboot, I have to manually open each program in that target desktop to make it look like it did before.   So, I'd like to write a .bat file that can get all my programs running in their appropriate desktops. I'm wondering if something like this is possible:  "C:\Program Files (x86)\Mozilla Firefox\firefox.exe" -desktop:2 "C:\Program Files\My\Other\Software.exe" -desktop:3 ...etc.   Obviously, this example is not real, but I hope there's something similar. I don't care if it's hacky :) How do I clone a generic List in Java? How do I invoke a Java method when given the method name as a string? How do I undo 'git add' before commit? I mistakenly added files to Git using the command:  git add myfile.txt   I have not yet run git commit. Is there a way to undo this, so these files won't be included in the commit? Prove the function is continuous, exercise from Conway's "Functions of One Complex Variable I" I'm considering taking a loan on my 401k in order to pay off and close 2 credit cards.  I have approximately 30 years until I consider retiring.  The amount of the loan will be $1700 which is less then 20% of my current 401k balance.  I will continue to put 9% of my paycheck into a Roth 401k, and my employer matches 9%.  The loan will be paid back at 3.25% (to myself) and does have $183 in fees.  There are 2 cards I will pay off and close if I follow through with this plan.  One card is 17.9% interest with roughly a $650 balance.  The other is 23% (ish) with roughly a $1,025 balance.  Both of these cards do have an annual fee associated with them, I used them to rebuild my credit and have a newer, lower interest, no fee card that I will keep active for emergencies.  Would it be advantageous for me to pay off these two credit cards and cancel them with a 401k loan? UK visit visa: What documents prove genuine relationship with the visitor? In the UK immigration rules for visitor visa  it states if;      Funds, maintenance and accommodation provided by a third party      V 4.3 A visitor’s travel, maintenance and accommodation may be   provided by a third party where the decision maker is satisfied that   they:      (a) have a genuine professional or personal relationship with the   visitor;and      (b) are not, or will not be, in breach of UK immigration laws at the   time of decision or the visitor’s entry to the UK; and      (c) can and will provide support to the visitor for the intended   duration of their stay.   I'm a UK  citizen. I'm planning to invite my brother-in-law and another close friend to the UK. In my invitation letter, I have clearly mentioned that I'm going to provide them accommodation only. They have prove sufficient funds to support themselves. I have sent them an invitation letter along with a copy of my passport and tenant agreement.   What other documents do I need to provide to indicate that it is a genuine professional or personal relationship with the visitor? Is $\{0\}$ a field? Consider the set $F$ consisting of the single element $I$.  Define addition and multiplication such that $I+I=I$ and $I \times I=I$ .  This ring satisfies the field axioms:   Closure under addition.  If $x, y \in F$, then $x = y = I$, so $x + y = I + I = I \in F$. Closure under multiplication.  $x \times y = I \times I = I \in F$ Existence of additive identity.  $\forall x \in F$ (i.e., for $x=I$), $x + I = x$, so $I$ is the additive identity. Existence of mulitiplicative identity. $\forall x \in F, x \times I = x$, so $I$ is the multiplicative identity. Additive inverse. $\forall x \in F, \exists y = I \in F: x + y = I$ Multiplicative inverse. $\forall x \in F, \exists y = I \in F: x \times y = I$.  However, because the additive identity need not have a multiplicative inverse, this is a vacuous truth. Commutativity of addition.  $\forall x, y \in F, x + y = I = y + x$ Commutativity of multiplication.  $\forall x, y \in F, x \times y = I = y \times x$ Associativity of addition.  $\forall x, y, z \in F$, $(x + y) + z = I + I = I$ and $x + (y + z) = I + I = I$, so $(x + y) + z = x + (y + z)$ Associativity of multiplication.  $\forall x, y, z \in F$, $(x \times y) \times z = I \times I = I$ and $x \times (y \times z) = I \times I = I$, so $(x \times y) \times z = x \times (y \times z)$ Distributivity of multiplication over addition. $I \times (I + I) = I$ and $I \times I + I \times I = I$, so $\forall x,y,z \in F, x(y+z) = xy+xz$   Based on the above, $\{I\}$ seems to qualify as a field.  If $I$ is assumed to be a real number, then the unique solution of $I + I = I$ and $I \times I = I$ is, of course, $I = 0$.  So, is {0} a field, or is there generally considered to be an additional field axiom which would exclude it?  Specifically, is it required for the multiplicative identity to be distinct from the additive identity? How do I write a cpp macro which expands to include newlines? is this set a regular surface? I'm reading "Differential Geometry of Curves and Surfaces of Manfredo Docarmo" I'm doing  the exercises of the chapter 2. Here is the definition of regular surface that we are following:   I have problems with this exercise:   Is with the first part, I think that it's not true that it's a regular surface (the second it is). I don't know how to prove that something is not a regular surface. How to install TP-LINK Archer T4U driver? I bought the wireless adapter to use with a computer without internet access but I can't figure out how to install it with just a USB with the driver on it. I've read a few articles on how to install the driver but they all require me to have internet access and I don't have internet. I'm completely new to Ubuntu. If you can help that would be great. Thanks!  Ps: I have the latest version of Ubuntu as of 7-5-16. Area of intersection of two Annulus Given two separate annulus with centers $[C_1,C_2]$ and their corresponding radii being $[R_1,r_1]$ and $[R_2,r_2]$ respectively, larger radius being $R$. There are methods to look at whether they are overlapping or not. If they overlap how to find the overlapping area. Is there any close form expression for it?  equation of first annulus   $r_1^2&lt;(x-x_{c1})^2 + (y-y_{c1})^2 &lt;R_1^2$   equation of second annulus  $r_2^2&lt;(x-x_{c2})^2 + (y-y_{c2})^2 &lt;R_2^2$  If there are three circles overlapping, we get overlapping area as solution to set of 4 in-equations by least squares approach(Though we don't end up getting total area but, area within tangents of circles ). Create ColorRamp How can I create a ColorRamp for a Cycles material through Python?  I am able to create a new shader output node with nodes.new(type='ShaderNodeOutputMaterial'). Searching online, I see that it is only possible through C code (however, these pages dates back several years).  Is there a way to fake a ColorRamp (maybe with multiple Math nodes in greater/less than mode) or create a ColorRamp for a Cycles material through Python? What is the best way to randomize the order of a generic list in C#? I've got a finite set of 75 numbers in a list I would like to assign a random order to, in order to draw them for a lottery type application. I understand the reasoning behind the fairly narrow textwidth in a default LaTeX article. 60-80 characters per line and all that. However, I am preparing a document that features many lengthy equations, and it seems silly to me to restrict the equations to fit into the same margins as the text when there's all that whitespace going unused on either side.  I'd like to have equations which are wider than the textwidth do the obvious thing, that is, continue to be centered on the page just like all the other equations, and simply extend into both the left and right margin equally. My equations are unnumbered, so there's no concern about where to put equation numbers.  How might I go about implementing this?
