Advanced Member stevecullum Posted February 10, 2010 Author Advanced Member Report Share Posted February 10, 2010 I guess the only way to export the results from a mulit-res Ptex paint is via Texture Baking? So far, unless other 3d apps offer support. I thought the results worked well considering the texture map is a complete patchwork of tiles! Need to test with animation next though. In anycase, the more popular this format gets, the more chance someone will write some import plugins. Quote Link to comment Share on other sites More sharing options...
philnolan3d Posted February 10, 2010 Report Share Posted February 10, 2010 If you saw my quote from the guy at Disney above, after seeing the 3D-Coat results he questions whether there is even a need for a ptex format. Quote Link to comment Share on other sites More sharing options...

Yep, I agree - it's quite workable for now, but I'm always after the best detail, so if I can see it around the corner I won't be content to settle if I don't have to If you saw my quote from the guy at Disney above, after seeing the 3D-Coat results he questions whether there is even a need for a ptex format. Maybe that is in another message from him? I didn't read that into what was quoted anyway. However, there seem to be some pretty clear advantages to Ptex from what I have seen so far so not sure why he would say that. b Quote Link to comment Share on other sites More sharing options...

Advanced Member simmsimaging Posted February 10, 2010 Advanced Member Report Share Posted February 10, 2010 The first line of his second paragraph: "One of the questions that seems to come up is whether the Ptex file format is needed or not." I read that as a question often asked of him, not his POV. Either way though, he speaks to that pretty clearly just a couple of lines after that: "We tried sending these packed textures directly to Renderman at one point (before Ptex) but it didn't give us the performance or filter quality that we wanted. For us, the Ptex file format and rendering performance is critical." Given the accuracy/detail you can get with it, and the potential overhead control/drop if render engines support the format, why wouldn't this be better than PP in 3DC? Have I misunderstood things?

philnolan3d Posted February 10, 2010 Report Share Posted February 10, 2010 Well I do think the ptex format would be best, but it is nice to have the current method to use in the mean while. Quote Link to comment Share on other sites More sharing options...

Advanced Member pbowmar Posted February 11, 2010 Advanced Member Report Share Posted February 11, 2010 For us (film work) the Ptex format is critical. We'll be loading potentially hundreds of 4k textures in, the per render bucket access and optimizations of the Ptex format will be very important...

Fro 4k, and even 2k work, PTEX is very helpful for GPGPUs and non-gpu based render engines. I'm thankful Andrew added this feature so early on, and hope the major render engines add it ASAP.

philnolan3d Posted February 12, 2010 Report Share Posted February 12, 2010 To be clear when I was talking about "Ptex format" before, I meant the .ptx file format that Andrew has not yet implemented. Just in case that wasn't clear before. You can see samples of the format here: http://ptex.us/samples.html Quote Link to comment Share on other sites More sharing options...
