Hair and Fur driven by Corona distance map?

[Hilmar]

Hello
I have a question regarding some refreshing problems. Dont know , if caused be MAX or CoronaMap. Cant tell.


The idea is, to use a corona distance map, to drive the scale or cut lenght of the Hair&Fur modifier. I thought I could use it for... a rolling ball into a grass field for example. It would be cooler to get the grass/hair to bent to the side, but scaling em down to create something like a path would do it for me as well.

Using MAX2019 and Corona4

It works for the first time. Right after I pluged in the DistanceMap into the correct slot. But if I need to change something in the MAP, the map is set back to 0, like there is none. I mean, all the settings are still there, but in the render it seams like there is no map.
The only solution now, is to "cut" the map and paste it again. It will work for ONE render process only. So I have to paste again and again.

Any idea or tip for a workaround?
Thanks in advance for your help.

Maybe you can share scene to see what is wrong?

By the way why not to use tyFlow for that task? There is sample scene right with that scenario

Sure

Thanks for any help.

Tyflow…. ok, will give it a try. But I rarely used particleflow in the past, so it might be to high for me. But I will try :)
Thanks

I can confirm this too, looks like a bug.

I may suggest convert hair to mesh, or use corona scatter and scale

Hi,

Thanks for reporting this. It looks like the same issue which has been reported here: https://forum.corona-renderer.com/index.php?topic=24987.0

We are looking into this, but at the moment I don't have a timescale for a fix.

Thanks,
