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.

What's your graphic card and drivers?

You can set an environment variable to bring it back

Hi, I'm using NVIDIA GeForce GTX 285

I put “HOUDINI_OGL_H11_VIEWPORT” in houdini.env file, but I still can't get H11 scene renderer in Houdini 13.

Is H11 removed from Houdini ever since?

the images below show the problem with Houdini 13 scene renderer using the same file and the same olt.

image 1:
In Houdini 13, using GL1.1 scene renderer, the colors are totally different from the one in image 3 which is shown in Houdini 12 using H11 scene renderer (both in infra-red color scheme)

image 2:
In Houdini 13, using GL1.1 scene renderer, the primitive attribute values are not even shown in the Details panel.

image 3:
In Houdini 12, using H11 scene renderer, the correct display of color

I'm not sure if it's a problem with my graphic card or Houdini 13.

pls advise!

Yeah - H11 is now deprecated and the if you hconfig -H you can see it will be removed. i.e.:

HOUDINI_OGL_H11_VIEWPORT
Enables the H11 3D viewport renderer. 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 = 1


You 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.

H13 bug report submitted.

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