Wow, I din’t know you could use AUVs and GUVs in other programs. That’s really cool! I stand thoroughly corrected. :idea:
Thank you All for the feedback - much appreciated.
I have gone through the tutorials on the Modo site as well as the link that Buckie suggested. All the steps are the same as what I am doing. As I mentioned before, the problem is really with the GUV and AU tile mapping in ZB. Here is a test render in Modo showing the problem. This is Pixolators test head and is GUV mapped. AU mapping is a lot worse.
Thanks,
TD

I had a similar thing happen to me, but I can’t remember what I did to resolve the problem. As I don’t have ZB installed I can’t test it out. I do some searching & report back…
This was my thread from last year, I did solve it but can’t remember how… :mad:
Hi Buckie,
I checked out your link and that is the exact problem that I am getting.
If you have a fix then I need it now!
Thanks

Don’t forget in modo disaplcement map locator, to set the minimum value of the map to -100 (0 by default, leave the Max value at 100%).
If I remember, Brad Peeber did a video about the Zbrush 2 to modo 203 workflow… with this sample! Check the luxology.tv section of their website.
You know I think that was it… 
I can’t check it as ZBrush is not installed but I’m sure that was the problem, Totyo you are a legend… 
I’m not a legend at all, I just wrote what I read/watch somewhere else and experiment myself I had the same problem as you with my modo 301!
Edit: I found the video: http://content.luxology.com/modo/201/video/ZB-Basic-01.mov
Hi Totyo and Buckie,
I had already triple checked my settings in Modo and they all match. Just for fun I went back to Modo 203 and tried the render and it works without a hitch with the same settings! Same file in 301 does not! I uploaded the file in the image link. Main reason for wanting to get 301 working is it’s fast rendering of motion files using MDD data.
Any more light shedding would be appreciated.
Thanks
TD
please, can you provide a link to your mode file and the displacement map (or is it the Pixolator file just loaded in modo?)
Hi Totyo
The test files were the Pixolator head files. I have checked these files out on Modo 203 and they render without a hitch - in fact faster. This would appear to discount any problems with the obj or tif files. Just for the sake of inflicting further brain damage to self I went and adjusted every parameter in the scene and system settings - did not make any differance to the actual problem.
This may be connected, but when I bring in other files for rendering in 301 I was also noticing odd artifacts on the render with files that had a more conventional UV layout possibly in areas where there were seams. If you apply any other file as displacement ie a noise pattern within 301 then that appears to be clean.
I can email you the LXO scene files - if that helps.
Thanks,
TD
Im using Modo 301 and I havent had any problems with any dislacment maps. If using zbrush uvs I normal use GUV.
Here is a basic test using a Zsphear Uv ball.
Problem Solved!
I got hold of the the fix over at the Modo site. It appears that the in Modo 301 the Vertical Flip function is erratic and creates a missalignment. The ZB maps need to be flipped before exporting from ZB. When I did that it all works fine.
Thanks to everyone for taking time out to assist.

Sorry to quote myself, but I’m not often right…
Glad things got sorted though…
tez what are the setting you use to get the displacement map from zbrush?
i try so many.
they lok good from far away in modo, but when i get close i dont see all the nice detail from zbrush (like little veins, they look like if the map is very low resolution)
Pelos you may need to play with displacement shader rate settings under render settings to get finer subdivision.
Well first I see what size the mesh was in Zbrush to attain the detail that I have. Il set up the low to -100 and high value to 100 in the displacment map settings. On the material setting il take the Displacment distance up as high as needed, this depends on the scale of my model, often 600mm to 2m. In the render settings I will set the Adaptive sub D up or down according the the size mesh its producing ,at the distance of the my finnal render is to the camera.
I will play with the MicroPoly setting bringing it down slowly untill fine detail is shown. Modo is one the best displacment and Bump renderers iv seen, I dont loose a ounce of ZB detail. Al my maps are 4k ones, I always enable Max button and flip on export from ZB.
tez thanks
that was very help full.
i will try that later on , when i get home.-
tez one more question,
what are the settings you use on the displacement,
4k max out,
but you use displacement exporter?
u set a 16 bit or 32 image?
and what settings?
thanks once again.
A video link will be posted soon as its rendered it. Here is the result from the video.
