Questions and Troubleshooting for ZBrush 4R3

[system]

Forgive if this question has been asked before ***8212; the thread is quite long, and a basic forum search hasn’t yielded any helpful results.

When using noise with an alpha & UV, none of the rotation sliders produce any effect.
They work within Noiseplug, but I have my own alpha I want to use…

I saw in the first post that they were having some problems with noise plug and some tablets. I use a small bamboo, but this is basic functionality that just doesn’t work? Is there something I’m missing?

Mac OS Lion. 4R3.

Hello, I’m not getting any feedback from zbrush when I turn on lights and change the light settings in Preview or BPR render modes. I just recently got back to using zbrush after a few weeks and noticed that this is happening and I wanted to check if there is anything that can be done. I recall this working fine just recently, now even when I turn the 2nd light intensity all the way up I see not changes in either preview or bpr mode.

Hello there,

I see you have the Red Wax Matcap activated. I don’t believe the Matcap materials react to lights (except for maybe the shadow direction when rendered). Everything else is pretty much baked into the matcap itself. Using the standard materials (basicmaterial, fast shader, skinshade 4, etc) instead of matcaps should give you a material that will actually interact with lights.

Hi, I’m having problems with refraction. Transparency in object Display Properties and in Render Properties and BPR settings are as below. The shot shows that transparency is rendering correctly but no distortion from refraction is occuring. What’s going on?

Firstly, awesome upgrade.

Secondly, how do you get Vector Displacements to show up in modo? I am exporting them as per the docs.

Thanks.

Edit: Solved. The problem I had was simply the Vertex map getting flipped on export, so I turned that off in Preferences>ImportExport>NormalMapFlipVert(off)

Edit 2: is there a way to turn that button off permanently? Storing Config doesn’t seem to do the trick, so it keeps switching on after a restart.

Here’s a link to a discussion of ZBrush Vector Displacement in modo on the Luxology forum:
