You didnt mention this in the release notes, but IES files now have an extra option if you click the spanner on the image node called "IES SCALING"


Hi, was this with a new scene? When loading a scene saved using 2020.2 it should be set to normalize the maximum to 1.0.


Roeland, Paul Kinnane sent me an alpha build of the modo plugin, and I was loading a previous scene. So the Octane API was seeing this as a "new" scene when it builds the nodegraph, setting IES scaling to "normalize using lamp luminance".

If I export an orbx from the 2020.2.3 plugin and load it into 2021.1 XB1 standalone, it looks correct, because Octane recognizes this as a file from an older version.

I guess Paul is going to have to set all images to "normalize peak to 1.0" to prevent older modo scenes from breaking.

OK, no problem, let me investigate to see if there's anything I can "fix" to correct this.

Thanks Wallace

If anyone here has a 3090 and can test my sample file with rtx on/off, it would be appreciated:

We can also reproduce it using a 3090 here. We will investigate and hopefully get it fixed for the next release.

Thanks Mojave. Were you also using 466.47?

Im just curious if I could fix it by using other drivers.

In my case I could reproduce using 465.89 which are also causing other issues currently under investigation.

Be aware the latest NVIDIA Studio drivers for this card are 462.59 although didn't get the chance to try those with your scene yet.

BUG: Clipping material stops working if camera is inside surface

I have an example with an animated camera moving closer to an object, which eventually goes INSIDE the surface that has the clipping material.

Once the camera is inside the surface (frame 22), the clipping material stops working

If Specular is accidentally hitting 0 in the Node Inspector when adjusting, the AI scene starts to reload which can take a long time. If it doesn't hit 0, the scene update normally.

I reported this behavior in closed BETA. The team told me fixing this could potentially increase rendering times. I suggested a switch to turn on/off rendering clip when camera is "in". I don't know if they plan on implement it.
Regards,

EDIT: What I wish to see, in addition: to have Octane default materials set intersection priority to "0". It is easier to set one clipping material to a value higher than "0" than to reset individually all scene's materials bellow 100...

The camera will be fixed before the final stable release.

For your last point, the materials' default do have a priority of 0 by default (not 100), only the clipping material has a default of 100 priority. At least this is the way standalone is doing it.
