3ds Max Arnold Procedural Placeholder Box dimensions

Greetings to everyone,

Hope all of you out there are doing well!

Here is my problem. I have created a few procedural geometries and saved them as ASS files. Then I create a procedural object; click and drug on the viewport to create the Placeholder "cage"'; then I hit on the Path button to load any of the aforementioned geometries that I made. The geometry is loaded successfully and it is rendered as it should be.

However, the Placeholder "cage" (or box) does not alter its shape according to the limits of the loaded geometry - hence it remains a cube with the dimensions initially given when I dragged in order to create it.

Does anyone have a similar problem or any idea on how to fix this? It is of great importance because I have multiple geometries that must be neatly arrayed in the future.

Best,

Adam.

PS. Using 3ds max 2018 (however, I noticed that the same issue is caused in the 2019 version as well) and the latest version of Arnold.

Yes the cage isn't changing, witch it should.

Maybe link a non renderable proxy mesh to it to see it better in the viewport.

Use the active shade to preview it.

Manually set the cage dimensions. Until they fix it. ;)

Thanks a lot @Michiel Van Gasse,

it is just one of these occassions where you think that are probably doing something wrong, until you figure out that there is actually a bug in the system. :(

I see that the 2020 version is the same bug. Has nobody improved it over the last 2 years ?? It seems to me that Max is not modernized, Maja has a working procedure.
I use Vray in my professional work, but I also teach students on basic 3ds max without additions and improvements and this is a nightmare, something is still not working as it should.

Anyone even read these entries ???

When will the Procedural Geometry Bounding Box be improved ???

Right. However, according to what I have seen so far from the tutorials, the shape of the cube that defines a procedural, should change; for example, if the procedural geometry is an object with a height of 50mm, the proxy cube should have a similar height. If the procedural geometry is an object of 700mm height, then the cube should alter its height accordingly. However, no changes take place no matter what the size of the procedural geometry is.

Correct, the size of the box does not affect the procedural size. However, its scale, rotation and translation should.
