Chaos Corona for 3ds Max => [Max] I need help! => Topic started by: Siggicz on 2023-06-30, 14:20:35

Hello everyone,
I searched for a long time but unfortunately did not find this problem.
I have been processing 3d visualizations in a combination of 3dmax and Vray for almost 20 years. Lately, we have also been working in Corona at the same time. I would like to ask about masks, render pass in combination with ForestPack. Is there a chance to render my RenderID, Mask, whatever when there will be one color to select in PS? Anyway, how does it work in Vray?
Each object in Forestpack is always rendered separately, by object, etc.
Entering FP into G-Buffer and the same into Mask in render passes does not work either. (I cant add G-buffer for xrefed files)
The same for render selected, when I want to render only the selection, Forest Pack never renders. I only have the main FP object selected, the objects in it are xrefed and therefore cannot be selected?
Is there a solution to achieve the same render pass as I'm used to from Vray? I Just need to select "all the trees" from one FP in PS and make color corrections.
Thanks in advance!

What we usually do is this:
Right click the forest pack and select "Select all Forest Dependencies".
Click RGB Mode in the Mask Elements so that you're able to separate the channels.
Click Manual selection and add all of the selected forest dependencies to the R G or B channel.
Now a mask with pure R G or B will be created for the forestpack. You might have to deselect an object if it interferes with the greenery and won't create a good mask, but it works 95% of the time.
In photoshop, to select it, just CTRL click the respective channel in the mask element, to select them very precisely.

Suppose you're using Forest Pack to scatter three types of trees and you want to create a render mask for trees of the same type, you could use CMasking_ID. You'll find an option there called "Geometry group ID" - try selecting that.
And if you want to create one mask for the whole Forest group, it's pretty straightforward too. Just right-click on your forest object and select "Select all forest dependencies." Then, right-click again and go to object properties. Here, you'll find an option to set the G buffer object ID. Once that's done, you can go back to "Cshading_mask" and set the object ID to the same G-buffer ID.
I hope this helps.
