Linear Workflow Checkbox Information

[yolov]

The amounts are multiplied by the input and then corrected. We take the input, pass it through a multiply/divide where the multiplier is taken from the amount value/input, then passed through a gamma node and plugged in the color. Then the amount needs to be set to 1.0 in the scene.
Will you need to use this in the builds from version Next?
We will include a conversion with V-Ray 5. We're actually almost ready with it and we handle the amounts there too.

We were getting prepped and were intended to have old assets ready to go before the release of 5. I think the amounts were the last piece of the puzzle I think. Do you all have a rough idea of when vray 5 is going to release?


Is your tool working enough that you could pass it over for us to use on some tests?

[yolov]

We are polishing up a final few things on our tool. It is built-in V-Ray 5. I'll look into sharing the code, it uses the OpenMaya python module.
Yes, the amounts are the last piece of the puzzle. We aim at releasing V-Ray 5 in the upcoming weeks.

What version of V-Ray would you test this on ?

[sdelalla]

We would most likely test on vray 4.12.02 with "use legacy materials" checked off.

We also have 4.30.xx versions installed if we need to use that. Is there any key differences?

[yolov]

OK, here's our code, I've modified it to (hopefully) run on 4.3 (at least it does in my tests). If you come across errors in the code, then it will be best to test it in V-Ray 5 directly, but let's first see if it runs in 4.3. It will further take time to make it work for 4.12, so I suggest using 4.3 for this.

Ideally, you just need to execute the attached code in a Python tab in the script editor on a legacy scene. The code calls migrateLinearWorkflow() at the end, which executes the migration.

Let me know if it works.
