Painting Issue

Anonymous — Thu, 24 Aug 2017 17:01:01 GMT

I just got Mudbox. I keep getting this noise when I paint. This happens with any mesh including the default ones. If I decrease the size to 512 and increase to 16 bit, I can paint with only an occasional artifact showing up. Is there another way to resolve this? Thanks.

I'm 99% sure this is a problem with the graphic card driver. Are you using the latest version? What kind of graphic card is it?

Yeah, I was afraid it might be. I have an Intel HD530 and the drivers are up to date. If I reduce it to 256 pixels, the issue disappears. I might have to make do with that until I can upgrade. Still, I'm happy with Mudbox and find it more intuitive than Zbrush. Thanks for the response.

I'm having the same issue right now, are there any other solutions I can try? I can't reduce my tex size, I need 1024 or larger often. My graphics card is a GeForce GTX 1060 3gb, all drivers up to date. Tried also with a GTX 1070. Running an Intel i5 at 3.2 ghz, 16 gb ram. First had the issue with Mudbox 2018, same issue in Mudbox 2017. I can't think of anything else it could be, and it's driving me crazy! I can't complete my textures, it's so bad!

Hi there,

I have not come across this issue before on an NVIDIA card. We have a bug logged with Intel for Intel graphics cards, which is where we've seen this before. I will see if we have your card in house to double-check - we should, as it is on the currently tested hardware list. Is it at all possible you have a second card the software could be using?

Confirmed with QA, we've only seen this on Intel. Are you running a laptop? If so, you probably have two cards, and are using the wrong one. Take a look at this thread:

Hi Jill, thanks for your reply. No, I'm on a desktop pc. I don't have two graphics cards, but we did swap my original GTX 1070 for a 1060, thinking it could be an issue with the 1070s (no luck). My two coworkers use a GTX 1050 and GTX 950 and have no issues, but they also have 32 gb ram whereas I only have 16, could any of that cause this sort of problem?

No - 16 GB RAM should be just fine. This is very strange, as both those cards are tested and we don't see the problem here. If you've uninstalled and reinstalled the drivers, I can't think what else to suggest. I will check in again with our QA team.
