Shadow casting invisible objects Tweet

[Isotemod]

Hi I was using an exported scene and I noticed in the stand alone I could set an object to be invisible to the camera yet still cast shadows.

Is this possible from within the plugin?

If its not consider this a feature request.

Please note this is not invisible objects receiving shadows as per the sticky topic.

Hi - I just posted a pre-release (version 3.6.2.32) of the next version of the plugin which includes the Camera Visibility ON/OFF parameter.

Thanks for the speedy update.

Hi

The visible to camera property doesn't seem to work in animations.

I tested a simple scene and the object made invisible to camera is visible during animation but not during normal stills.

Can you take a look please.

The Visible to Camera property is always read at frame 0. If the number of mesh items, or vertices change during an animation, it breaks the vertex motion blur obtained whilst exporting the scene to OCS/ORBX. If you need to make an object invisible during an animation, set the scale to something small or move it out of the camera view.

Yep that reply went right over my head.

I guess I need to give a bit more info.

The animation is being handled within daz studio using the animation tab in the octane plugin.

The scene at its basic has an object that is set to invisible to camera and a plane with a specular transparent material on it. This allows you to see the invisible to camera object as it passes behind it.

A static render is fine but the animation option in the plugin appears to not use the camera visibility option.

My apologies - that reply was for the Modo plugin!

Can you send me the scene pls, and I will take a closer look.

Hi - I have looked at the scene you sent me. Unfortunately none of the plugin animation systems (ie. Animation tab->Start Animation, or System tab->Alembic Export->Start Export) support the DAZStudio mesh OctaneRender:Visibility parameter. This is because these systems are effectively operating in Final Render mode - where all meshes are combined (so there is no individual mesh visibility control) - regardless of the Preferences->Use Combined Mesh setting. This is a plugin limitation, which cannot be resolved in the near future, sorry.
