Help Scale Issue

[josemendez]

I tried changing the scale in BluePrint but It doesn't effect, the object is occupies same amount of space.

Hi!

Make sure you re-generate the blueprint after setting the scale value. Changes made to blueprint parameters won't take any effect until you generate the blueprint, this is akin to baking a lightmap: changes to lighting settings won't have any effect unless you rebake the light map.

Also keep in mind that the blueprint's scale determines the size of the cloth. The transform's scale should be left to 1, and the blueprint's scale used instead. This is because affine transforms in general (and scale in particular) only work with rigid objects, not deformable ones. So the scale of the object should be set when generating the cloth data (when it's still rigid), same as it happens with Unity's built in cloth. The only difference is that Unity re-generates its cloth data every time you press play, while in Obi it is generated in-editor and stored in an asset which is far more efficient.

Also related to scale: keep in mind that you can scale the simulation space by scaling the ObiSolver's transform. This will rigidly transform the entire simulation, which is very useful when you have eg. multiple sizes of the same character cloth. This allows you to reuse the same blueprint at different scales.

kind regards
