Hi , good morning everyone.

I got stuck and ran out of ideas and online help for a problem i have in a pipeline,
with applying a displacement texture onto a fish. :shrug:

If anyone has an idea to hare or did encounter a similar problem, help and hints are very appreciated.
Thanks a lot for your time :)


..I have this fish to be animated in Maya, which i used Luxology Modo for giving it a displacement map, whereas my collegaue does the shading and final rendering in Cinema 4D. *
In order to do so, I need to export my animation from Maya in .fbx-format. However, it seems fbx does not export the Mesh's UV set with any export-options (fbx-plugin updated), the work-around was (in C4D ) to take the UV sets from the Obj and apply it to the fbx-imported Mesh. Unfortunatelly, whilst the Obj renders fine with the displacement in C4D, the fbx mesh behaves diffrently, even as the UV set and the wire seem to be identical.. =(

1) displaced fish in MOdo, the way it is supposed to look:

2) The displacement applied in C4D, distorted and out of place

3) c4D textured view with the checker to clearify. the Obj is smooth, yet the fbx mesh ruined.

4) In the c4D UV editor and wire-mode everything looks as it should ...

5) Comparison between the Obj and the fbx-mesh. (c4D)

Does anyone have a clue what causes this ?
I dont have a great deal of experience with 3D or texturing, i hope it is something simple ;)

best regards, M

Are the fins animated or is it just the fishes general direction/orientation?

Does the version of c4d you're using have AR with the sub-poly displacement feature?
If not, that could be why.

Are you using the riptide plugin for cinema?

I don't know anything about fbx animation so can't help ya there.

Maya>Modo>Cinema is a bit of an overcomplicated pipeline though don't you think?

Hi,

first of all thanks @cameo and detox for trying to solve this puzzle with us...
there must be a way, i did a search here and found no post regarding
maya>c4d fbx problems wit UVs. Most people seem to have problems
if so with their rigg coming from maya. lucky we dont have that problem!

simply copying the uv map from the obj didnt seem to work..

using Riptide solves this problem!
Now the Map from the obj fits on the Fbx imported mesh, thanks again Dtox:)

@ Cameo: Cheers, iam not sure if i understand your question completely, about the general orientation; well yeah, the fins will be animated, they have a bone-setup with automated keys even, u can set 2 values for each fin (for velocity and amplitude) and he swims until kingdom come.

@Dtox: Cannot tell u about the version, but AR is used.
In fact, the riptide-plugin did the trick. it was about the obj, not the fbx after all, and without the riptide, the UVs have gotten messed up somehow. so thanks :)

-> fbx mesh with the riptide-plug loaded into c4D.

..about the pipeline, thing is right now, me and my colleague work 1500 miles apart, using diffrent software and OS, and have to manage in a bit weird circumstances ..albeit Modo's sculpting/painting tools are quite nice (not saying stable-runnning) i definitely agree with you very much.

so thanks for the replys and help,
best regards. m

Glad you got it figured out.
Seems like everytime I turn around lately the riptide plugin is winning hearts and minds.
