I had waiting form 2010 2011 2012…

I want mudbox can paint on a low-res modle (like in game modle) with no error.

error means:if brush is very small (1 to 4 pix) bursh can not reach to the modle surface.so nothing can paint on center of face ,but edge or vertex area can be paint.the area depends on size of brush.
if brush is large,it was good,very good,fast,smooth,everything good..
can it happan in small size?game texture painting really need this.

otherwise painting is just for hires modle only ,for game textruing, it is useless.

What’s your scene Size and the Size of your model?

to be honest, i don’t really get your issue.
i got no problems with low poly meshes and small brush sizes, even with meshes quite lower than the t-rex.

and you’re using the try brush. this brush makes only sense with high poly models (micro details), cause it only paints on the lowest or highest area on a mesh!

Ah yes, I didn’t notice that. Yes, you’re using the drybrush which is specifically designed to only paint on the topmost edges (or lowest cavities when inverted). It’s for highlighting raised areas. So it’s working correctly, you’re just using the wrong brush.

Also you’ve made a weird falloff there. The curve goes from the centre of the brush on the left to the outer edge on the right. So it should start high for full effect at the left and drop to zero effect at the right edge. What you’ve made is a ring shaped falloff that is zero in the middle, goes to full effect half way across and then drops to zero again at the outer edge. That’s probably not what you want.

Hi all :

I did konw dry brush will draw like that ,but i am not using dry brush then, i am using paint brush.(first paint tool,does that brush have any dry brush opiton?)

And it should be note that not all low res model can not be paint .just some model with round surface but low res(like picture above in T_REX )

If want to see that , may should be two condition:
1,T_REX model in sampel file.
2,2048 texture with brush paint tool (pensize 0.3 )

Try this ,I am sure you will see what am saying about:)

In sample file _cube ,it is low res but it can be paint like what I expect.

Best Wishes
