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'm new to Blender and wonder why, when I render the image, the image is noisy or blotchy.  The render result is shown below.  You can see the effect clearly at the skin area.  Can someone help me resolve this issue?

For some reason, when I render out the image, it is plain white. I've checked the sky settings, and I tried applying textures, but nothing seems to change.  How can I fix this?

I know I'd probably use a combination of Noise Textures, but I have no idea how I could make it look realistic with varying combinations of random dots, scratch- and hair particles etc. I could only find some explanations on how to achieve standard film grain, nothing too detailed.

This is my Minecraft Animation. It is made in Blender Internal and is intended to be rendered in Blender Internal. The animation consists of me running infront of Minecraft trees. These trees are mapped with UV textures of Minecraft Leaves with alpha turned on so that the leaves are transparent in places. The Animation starts at frame 8 and ends at 40. This is not a case Z fighting.  However when I render the animation I get square alpha (sometimes black pixel) artefacts in the render. Every frame has diffrent result but still has the artefacts. This is what it looks like. The white is the alpha. Open in a new tab for closer inspection.    As I said some frames have this problem and some don't    This one has AA disabled. This makes the alpha only one pixel each. (Open in new tab to see individual pixels)   This problem does not occur in the rendered mode viewport.   Leaves' Material Settings     Leaves' Texture Settings     Edit: I decided to restrict the leaves from render and this is the result I have. Pretty ugly. Also added, glare and vector nodes just fyi.    I then decided to remove the wood as well and now this happened.    And now there's black and alpha.    Here is a link to a  showing the problem.  What is going on here! Is this blend file corrupted? Please if you know the answer or what causes this please mention this down below.  And because you asked here a stripped down version of the file:

When blender is rendering I can see my model but at the very end the render goes black and the image saves as a black image. I am using cycles. Any help would be awesome!

Okay, so this thing, is for me very strange. It still might be very obvious, but I started with blender 4 days ago.  So what is happening is that when I am rendering my animation, I have a white wall and ground where the scene grid is.  Here is a screenshot when in render mode:   And here it is in material mode:   I would really like to remove this, and I have tried for hours now with no success. I tried to unlink "world" from the scene but then it got all dark when rendered.  If you have any idea of what could be causing this?  (I am making an animated minecraft intro)  Edit: I was told to do alt + h and then the wall and the ground was visible in material mode as well. Here is a screenshot.    But I can't find a way to delete it...  :/

hi, why the model looks weird. no double face or normal flip?  I include the blender file

I have this model, and when I add the subdivision-modifier:    it seems to be okay, for me (I guess those bumps are there, because of the triangle faces instead of quads):    but when I add the smooth-shading I'm having this:    I think this is something really obvious -- but I just can't figure out the reason..  Thanks in advance,

I have been looking all aver for this problem and haven't run in to what this is... Normally I mark my seems and I get a nice UVMap ready to texture but sometimes I get this and it is just kicking my butt trying to find a fix.   Sorry if someone already asked this. I just couldn't find what this is and why it only happens sometimes and what is causing this.

I'm pretty new to blender and used it to model a castle and print it. Now I want to extend the model by textures and render it, but even when I render it with basic material i get some strange output.  Does somebody know my error? I already corrected the normals and they look fine.

I made the eyelashes for my mesh and though it will be fine as it looks in the picture     Particle Edit Object mode but after I render the eyelashes look very messy like this  What I am doing wrong? Here my Hair settings  Thanks in advance

I am kind of new to the whole animation aspect and in fact still in high school.  I am trying to make a Minecraft character rig and I want to make some 3D hair. I did not know how to quite make it so I kind of when just did something pretty simple. It isn't the greatest in any means, but any how the point is every time I render it white lines show up between objects or joined objects. I don't know how to fix this and would like help (a picture is posted below of the problem).

Because I am pretty new to blender I watched the tutorial  from BlenderCookie.com.  I loaded  onto a sphere but then in all views the texture is just some kind of blurry with no details.

I am admittedly new to Blender, and of course cycles. I am working on a scene and I have textures set to my objects that render with internal engine just fine. However, when I go into cycles, everything is greyish. I have two light sources that should be sufficient (I think), I just don't know what I'm doing wrong. This is a screenshot of the cycles result.

When I try to render a wave, it keeps being rendered in extremely low quality. I'm not sure exactly which setting is causing this, but increasing the renderand viewport sampling don't seem to help.

I feel I am nearing completion of the tutorial but am still having gaps in knowledge on how to render light properly. 2.92.0 blender file:  Overview layout:  Lamp:  128 sample before denoise:  128 sample after denoise:  1024 sample 1080p 100% render before denoise:  1024 sample 1080p 100% render after denoise:  I've been trying different Light paths, but I honestly don't understand the extent of how they interact with each other. I haven't seen any example of what those numbers should be in the tutorial either, if someone knows please let me know.  but it is now again a little bit too opaque, dunno when that happened. :D Not too sure what I am missing out so any suggestions would be lovely! Thank you in advance
