Map channels for distribution maps don't work

(1/4) > >>

Sacifair:
I tried almost everything but couldn't get what Itoo promised in this video: https://www.youtube.com/watch?v=IZbvlPd7_Nw&t=1s.

Basically, it's about using multiple map channels for the distribution maps feature in ForestPack 9.1.1.

If you look at the video link above, starting from 1:39, it is now supposedly possible to control it with UVW Map channels (for example, 1, 2, 3).
But I still believe it's not possible because you have to specify these channels somewhere, which ForestPack doesn't allow you to do.

Asking for help!
You can also read the comments under the video related to @sacifair. I mentioned that problem there.

3Ds Max 2025.1.

Hi,

In my quick tests, everything seems to be working fine. Please double-check that the Surfaces > Auto checkbox is enabled to ensure the distribution updates automatically.

I hope this helps.

Best regards,

I checked this, and the only UVW modifier that has any effect on ForestPack is the one that has the same map channel as specified in ForestPack's custom bitmap slot 'map channel' section in the distribution rollout. Note that this is in UV Mode.

Though XY Mode itself doesn't follow the same pattern as the distribution map channel does with UV Mode, it works based on the specified bitmap map channel (not the one under the distribution rollout of ForestPack). However, the issue remains the same: only one UVW Map modifier works at a time, and it must have the same map channel as the custom bitmap used in the distribution rollout.

I have attached a small video where I tried to demonstrate this issue.

On the other hand, could you share your process or maybe record a small tutorial on this matter?

Sacifair:
Any quick answer perhaps? Anything.

Michal Karmazín:
First, I apologize for the delayed response. Please note that multiple UVW channels are only supported in XY mode. In UVW mode, you can now specify which channel to use, as it was previously locked to channel 1. As mentioned in the Release Notes:

* With Surface XY mode, Map Channel is no longer needed. The distribution map is evaluated for all channels of the surface.
* Surface UV mode is no longer limited to map channel 1. But multiple channels are not supported.I hope this clarifies it!

Best regards,
