[Bf-cycles] Cannot update object transform

[F Escobar]

Thank you unfortunatly I'm getting undesired behaviour.

newTfm is my desired global tranform.

I've tried
sceneObjects[index]->tfm = newTfm;
sceneObjects[index]->tag_update(scene);
sceneObjects[index]->apply_transform(false); //this seems to be mandatory!
and
Transform ioldTrans = transform_quick_inverse(sceneObjects[index]->tfm);
sceneObjects[index]->tfm = ioldTrans * newTfm;
sceneObjects[index]->tag_update(scene);
sceneObjects[index]->apply_transform(false); //this seems to be mandatory!

But no one worked for me also sometimes it generates shading glitches on the meshes asociated to that object.


Regards and thanks for your valuable help, F.

Hi,

Use this:

sceneObjects[index]->tag_update(scene);

In general, scene updates can be done like this:

scene->mutex.lock()
... modify scene and call tag_update() ...
scene->mutex.unlock()

if(scene->need_reset()) {
    session->reset(...)
}

Regards,
Brecht.

I've added some custom objects via code to the scene, but now I wanna to move them and I didn't found any way.

Obviosly I start setting their transform with
sceneObjects[index]->tfm =newTfm; //tested that they are not the same transform.

Also I tried several functions that sound promising but without luck:
sceneObjects[index]->apply_transform(true);
scene->mesh_manager->need_update = true;
options.scene->params.bvh_type = SceneParams::BVH_DYNAMIC;
options.session->update_scene();
options.session->reset(session_buffer_params(), options.session_params.samples);

Anyone could give me a tip?

Thank you in advance.
