OK. So I have a question for the Sculptris Beta Team. I am desperately trying to apply painted textures and bump maps painted in Sculptris onto meshes from Blender. I have modeled what I needed to in Blender, exported it as an .obj, and imported it into Sculptris, painted the texture, saved it as the texmap and the bumpmap. Then back in Blender, I applied those textures to the model, and it seems like there is a UV issue. There are some tutorials I found on how to apply textures painted onto models in Sculptris. But those models were made in Sculptris, and not Blender.
I guess what I'm trying to figure out is a work-flow FROM Blender, TO Sculptris, and back to Blender. I just want to use Sculptris for the painting part, and apply those maps onto the 3D models MADE in Blender.
I'm not on the beta team, but i use very often Blender + Scultpris, it's a great combination for me.
After you painted, you say you saved the texmap and bumpmap, but have you actually saved the painted model itself ? From what i read it seems you're trying to apply the painted texture on the original model and not on the painted version you created after painting it in Sculptris.
The workflow to follow for a working (did it several time myself) is this :
-create your model in Blender.
-export it as Wavefront OBJ (important that the model has no non-manifold problems or it will crash Sculptris, at least the current version of Sculptris) -import the OBJ into Sculptris -Sculpt it if you want (not required, you can skip this step)
-Go it into into Paint Mode, it will generate an automatic UV map for it, and then paint your object.
-Once done, save the texmap and bumpmap you have done -Export the painted model into a new OBJ -Import the painted model into Blender, assign the textures.
Hi sanc. Thanks for your reply. Well, this is the answer I was looking for and I still can't seem to get it right. I follow the exact steps you tell me, and for some reason when I apply the painted texture to the exported model from Sculptris, the texture map still comes up wrong. It applies but not the way I painted it. It just applies it as an image and it looks all screwy. Man, you must be lucky. I'm also now having trouble even importing .obj's into Scupltris. could you explain a little further by no non-manifold problems? Thanks
edit : i just noticed you solved yourself the problem. I just let this here in case someone else has such difficulties too.
When in Blender, when you assign the texture, have you set the "Map Input" in 2.49b (or "Mapping" in 2.56a) to UV ? By default it is set to "Orco" , making it so the texture does not follow the UV at all, could be what is making your texture going wrong.
In 2.49b, it is in the Material tab :
In 2.56a, it is in the Texture tab :
In case it's not it, can you save (in Sculptris) your painted model as a .OBJ and upload it somewhere with the textures so i can try to give a look ?
To see if you have non manifold part in your model, in Edit Mode, unselect the whole model and click Select -> Non Manifold (same in both 2.49b and 2.56a) If you have non manifold areas vertices part of them will be automatically selected, allowing you to see the problem (often they're open zone in your model, like there by example areas you just have to close to fix it).
