I’m pretty sure this isn’t a bug but it’s driving me crazy and I need to know if it’s a software, computer or cockpit issue.

I created a mesh in XSI and when I try to paint a bump map on it the brush strength behaves as if it is set to max but the same brush and settings paints just fine on a Mudbox 2009 created mesh.  I’ve attached a screen shot showing the problem.

Does anyone have any idea what’s going on or how to fix it or workaround it?

Did you assign a unique shader to each object? And change the bump strength perhaps for one material?

Could you tell us if you scaled the object or transformed it before painting?

Yes, the model was scaled. When I imported it into MB it came in so small compared to a MB head that I scaled it up from within Mudbox.

I just tried it again without scaling and the brush painting appears to behave, then I scaled it up in MB and the brush problem comes back.

I’ll scale models before bringing them into MB, this is a workaround I can live with.

Thanks

Potential Bug:  Painting does not cover all areas of mesh

Here’s a link to the source MB scene file:

Possible Bug:  Tiling Stencils don’t work in Paint Projection Mode

When using Projection Paint, tiling the stencil does not work.  It only allows you paint over the single tile of the original stencil.

Potential Bug:  Painting does not cover all areas of mesh

The problem was your UV’s.  They were simply too close to the edges of the tile (I always leave a 2-4pixel gap between each island and also the edges of the tile.) There were a couple of other minor UV problems as well but those were not the cause.  Also your mesh is a bit tiny to be frank, So I’ve included a image to show the difference in scale between the default human base fro mudbox and yours.  This has a very big effect on how mudbox operates...so scale it up a fair whack , export the obj back out and then reimport things again and this will solve the size issue.  If you dont scale it up the sculpting brushes may well seem hyper sensitive and way too over blown.

Hope that helps.

Hi there.
Here are a couple of bugs.

Selection won’t work
Goes for all kinds, even select-all and is object-specific. The workaround I have found is to drop and then go up one subd level, or to add a new level. After doing so, selection will work fine again for that object. This happens very frequently. I can still sculpt those meshes, just not perform selections on them. I have a feeling it might be objects I don’t modify in mudbox but are static subdivided parts of the scene like armor pieces and such.

“Unfreeze all” critical problem
XP32: I get an “An unknown error has occured...” message, and can continue working on the model
XP64: Unfreeze crashes mudbox like in the screenshot below.

EDIT: Invert freeze crashes on XP32, same as in the screenshot

This happens regardless of whether anything was frozen to start with. This doesn’t happen when I load a clean scene with the mudbox head model.

Let me know where, and I’ll send you a file that illustrates both problems.

If the Active brush stamp image file is removed, mudbox crashes on startup. not a major one but something you might want to look into nonetheless.

Thanks Wayne.  Yes that helps a lot.  I re-watched your excellent stater videos and indeed the model I’m using (DAZ V4) is very. very small.  After scaling this up by 100x, the problem went away.
