I have an 8800 GTS, you can see how it works for me in the YouTube video I posted above.

Its fast enough and screen capture must even be sucking some fps...
Maybe Maximus3D is stuck in the "twilight zone" or something..

Maximus3d:Can you post one of your meshes?Its the only thing that hasnt been tested yet.
Phil could try it and see how it works using exact same build,with same graphic card and same mesh.

i guys i have some problem but in the same room ptex perpixel e microvertex, but only if the model is lowpoly..
In hig resolutions of the obj the brushwork is quick and precise.. ythe problem is with the lowpoly model!!
I have i7 with ATI 4850

[Maximus3D]

This is not the same mesh as i used, this one has a slightly higher polycount than my mesh. But test with this and see how well it works, if it works at all..

Works just fine. Though 3DC could use a little speed up when importing models for Ptex.

hi Maximus3D, your model in ptex paint works fine relly good, my problem is with the lowpoly model
Huge cage work fine, lowpoly is very slow in paint mode

[pbowmar]

OK I stand corrected: 3.2.02 on Linux 64 does not have the Ptex resolution change icon. Please see attached screengrab.

It does work on Windows.

EDIT: Actually it works fine, it is just the icon _graphic_ is missing. If you click in the space below it does bring the Res controls. So it's a minor issue if you know about it

Cheers,

import was fast for me and painting was also fast

i'm using Cuda 64 version not sure if that has anything to do with it

I'm sorry but what does Ptex mean? I read no uv's for painting. How is it different from Zbrush's automatic unwrap. Sorry for the noob question, just cant wrap my brain around it.

Well for me it means no UV unwrap, no seams in game engine (for 1st time!), and texture quality is better because the detail isn't distorted unlike when you usually unwrap things there is a slight distortion of detail depending on the unwrap.

you can see my forum pic thing to the left and there is big seams and stuff on it that appear inside of game engine idk why, but that doesn't happen anymore so that's just Ptex great

Another nice feature is the uniformity in size of the"ptels" over the whole model.

Hi guys my video...
in perpixelpainting with the lowpoly model my brush moves jerkily "fragments" not fluid

I'm pretty sure Perpixel's has always been slower with low poly. Because you have to put more texture information over a single face, but when it's high poly, you have less info to process for each polygon.

It was totally fine with a 1024 texture size. But then when I tried it with a 4096x4096 texture then I noticed my brush strokes had become considerably slower. It was still usable though.

I don't know if zbrush has this or not but it's also nice that yo can increase/decrease just the texture resolution in specific areas.

That is, when game engines support it. Great idea in general, only each ptex texture can only work specific to one model.

I'm also not sure how it works with triangles.

export to game engine works fine I've already tried it, it's just like Andrew said. Looks much better than UV unwraps did

How did you manage that?

File Export Model. And it works just like that.

[philnolan3d]

Oh When ShnitzelKiller said "when game engines support it" I think he meant support an actual ptex file, not just a model with UV map texture files. Obviously game engines support that.

hi kay_Eva, strange, in the video i use only paint diffuse, "no normal and specularity" is difficult to paint properlys, the brush moves discontinuously
