Why H11 scene renderer is not available in Houdini 13?

6146 10 1 User Avatar oat Member 479 posts Joined: Dec. 2009 Offline Nov. 21, 2013 11:53 p.m. It seems the H11 scene render mode is not available in the latest Houdini13? Is there a way to get it back? the GL mode is just not stable.

This renderer is deprecated and is going to be removed in the next major Houdini version.Try putting this in the environment variable:HOUDINI_OGL_H11_VIEWPORT = 1You should get the Scene Renderer as in the attachment. This is on OsX.Can you send a bug report in, just incase the developers dont see your post

Have you tried using the GL3.3 mode? You have a card capable of using it. GL1.2 is only for remote desktop work, or machines with software GL only. I'd expect it to be buggy, since there's almost no work/fixes being applied to it, due to its extremely limited use.

And the important 11th, once something is relegated to environment-variable status, you can expect it to be gone shortly thereafter. It is only still available to help people port old H11 GR render hooks to the new GR render hooks.The H11 renderer doesn't render the new DOP based POPs, packed primitives, alembic primitives or VDBs, so there is very little reason to continue to provide it.If you run into a showstopping GL viewport issue, please submit a bug so it can be resolved.

That difference almost just looks like a gamma difference to me. H13's viewport defaults to a 2.2 display gamma now, which might explain this. Try checking from the main menu > Edit > Color Settings.

The same Houdini file and otl will get different results in H12 and H13, and the H13 one is definitely wrong. Report
