How can I eliminate or reduce the white points in the rendered image?

I often use Cycles' built in Glass BSDF shader to achieve realistic refraction effects, but in many cases, it seems that Cycles' glass caustics creates an unfortunately large number of fireflies (pixels that are abnormally bright relative to their surroundings). In some models of mine, even when I render for 3000 or more samples/pixel, my final image is still covered in fireflies. While I can improve this in many cases by increasing the total amount of light available in the scene, this loses a lot of the potency of the refractive effects I'm looking for, especially in scenes with low light levels.  So my question is, how can I reduce the amount of fireflies while using Cycles' caustics without sacrificing the quality of the refractive effects?  Note: I am aware that Cycles' caustics will perform much better once Cycles has full support for bidirectional path-tracing, but it looks unlikely that that will become , unfortunately.

Hi everyone here a problem I have,  basically I want to remove all white from this image so I can paint beneath the illustration.  When I remove the white using magic eraser or the magic wand I'm still left with loads of 'white enclosed spaces'   &lt; this is my problem. It seems like I'll have to go into the image and use the magic wand individually for each white space?.  Is there an easier way to remove all of the white automatically?

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...  :/

I know that it's just a tiny graphic problem but do you also get a white line (or extra padding) after the last entry in the context menu?

was following a tutorial where I stumbled into this weird line in my mirrored mesh (sorry for the feet lol)      You can also download the blender file

I added an HDRI image (or also I tried, with Jpeg) but when I apply it, it only appears a single color. I think it could be from the image, but it doesn't appear completely as it should be.

In the image below you'll see the white section (highlighted blue). The black section behind it is one path, and the white another. How do I remove the white from the black so it becomes transparent? Hope that makes sense &lt;3

Cant figure out why the rendered image has a large black and white artifact (on the bottle on the right)?      Appreciate any tips!

I used Blender cycles to render an image, but the output has a watermark with some words in the top left hand corner.   How can I make it disappear by changing the related setting?

I'm trying to perfectly overlap two images, one complementary of the other, but apperas a white stripe in the conjunction of the path, all points are perfectly aligned how can I fix?

I found this image on  and quite a few have this vivid yet pastel effect.   Can it be achieved in Photoshop or Lightroom?

Can someone help me determine why my render is coming out in such low quality? I have Cycles up to 500 Render Samples, but I have no idea why it looks like it's only using one.

When I increase the point light radius, it ends up creating artifacts on the textures for seemingly no reason.  Even though I I have High Quality Shadows (High bit-depth and cube map resolution).  I want to create a smooth texture just like the corner of the photo, but for some reason it ends up creating these squares with what looks like many &quot;vertices&quot;.
