Exporting stress map
Hello
I want to export the stress map and fit map. Ideally I'd want to export them as an obj file with the information. Is there any ways this is possible?
Thank you

Hey Mike. I don't think that would be possible. The stress maps and fit maps are calculated live and to be able to export it as an OBJ it would need to be converted to a texture.
Certainly something CLO can look into.

It seems like they fixed the stress map update during the animation. I did not check, but I saw updates. When I had such a task, I took frame-by-frame screenshots of a 3D view and updated the stress map before each new frame.

Or are you interested in these maps in a flat form? Unfortunately, this is not yet possible.

Actually it is possible, has been for years,with sending the outputs to other tools. (many are open source)
including realtime grading of the garment from any avatar adjustment ( https://vimeo.com/359226270 ) to the full flatform dxf-AAMA compatible pattern > unwrapping in realtime, which is pretty funky.
https://vimeo.com/359229863 > note the texels in this example also change according to textile repeat patterns so the joints between fabric print design always look good between pattern panels in the garment. There is no texel distortion. Not easy to do.
In order to map the strain or stress to the 3D mesh, you need to have the object in the relaxed state (no strain or stress) and then the final output where there it is under strain or stress (simulated) , with a suitable gradient to represent the color mapped to a scale for strain or stress. So the avatar also represents one surface data set, and the clothing in two states, the other. A simple shape key between states then drives the vector vertex mapping change as scaled. See paraview software. Because CLO3D is an interactive (realtime) simulation space you need to record the change (eg: vertex weight map color ) from one domain space to your next system. Recording that vertex change in time steps, as mesh cache data using animation, is one relatively simple method.
So yes, very do-able.

ottoline would you mind elaborating on the method please, your videos show output not process.
am interested in the kind of mapping vadsura refers to in the comment previous to yours in this thread ie. transposing fit map from 3d space to flat mapping in 2d space.
thank you
