Having a problem with my texture paint showing up extremely pixelated and have no idea why;
The stencil image is 3000x3000px, and the image it’s being painted onto is 2048x2048.
Using 2.81~
And the UVs?
What about them?
Are they covering enough texture area? If every UV face is just a few pixels across, that might be the reason.
Oh, no - they are spread over the entire image properly.
Did you modify the max texture size in preferences?
Not that I know of…
Preferences>Viewport>Texture>Limit Size>Off - Is that what you mean?
Yes it is.
Take your texture into photoshop and bump up the image DPI to 300.
This is a dead thread, no response on solution for 4 years. Are you saying you tested the same scenario and got the same result except for using your solution of setting DPI for an image that isn’t using DPI in the process of Blender paint?
Hi Craig, I was running into the same issue and was looking for a simple solution. I had tried subdividing, but it didn’t seem to help with texture painting. I decided to check the dpi of the image and it was 1024 x 1024 but 72 dpi. I then knocked it up to 300 dpi, saved it and bingo bango it worked.
I will then see if I can find cause here since DPI is not an evaluation in the texture paint, nor in the render output.
I did a formal test on 6 images ranging from 1024 to 4096, 1 each of 8bit and 1 each of 32bit. The two images made in photoshop as 1024x1024 as a brush were saved as 72 dpi and 300 dpi, left side yellow is 72 dpi on 8bit target, orange is 72 dpi on 32bit target and right side blue is 300 dpi on both.
I find no real difference when comparing them projecting as stencil to the same size as the image plane. I think the next test will have to be done with a smaller subsection of the image texture on the mesh, similar to when big textures get projected to a few faces with very few pixels.
First 4 images for your review.
Maybe some clarification:
My issue was painting on an object, not using it as a stencil and I can only share what I experienced.
Using the texture paint was originally leaving pixilated edges. The texture for the object I was painting was at 72 dpi.
When I increased the texture for the object I was painting on, to 300 dpi, the pixilated edges disappeared. (naturally I generated a new UV ).
Very strange because Blender doesn’t ‘see’ the dpi setting of the image but the total pixels X and Y.
