Hi,

I'm having issue with shadows. The animation is working correctly, I have a test scene where I have a box bouncing and spinning, works just fine. But the shadows don't seem to be moving with my box, they are only reacting the stating mesh, they aren't taking into account the VAT animation.

Any idea what I've missed?

Thanks

Hi, having the same issue. And progress so far?

Hi,

this is not exactly your example, but it should work similarly. I was a bit confused aswell at the beginning, before I've figured out, that I've forgotten to merge the already calculated geometry to the new calculated tubes.
In your case you can try this aswell, by adding a merge node between sweep and foreach_end and connect it with the foreach_input node (fetch feedback), but there are probably other solutions aswell.

Thank you! That is working indeed. Exactly what I needed.

Hello everybody!

I'm new to houdini, and to 3d in general, and I ran into some problems. I will apprecite any help!

I want to create a simple procedural systems, where some kind of laying hoses are created from a given curves.
Also I'm taking into account surface where hoses supposed to lay.

So I am projecting original curves on the surface using intersect function in VEX. Then I'm creating pipes using sweep.
And I want to implement this algorithm to the curves one by one, so for every next curve all previous pipes will be taken into account when intersectint points are calculated.
The logical solution is to use for each loop. But I ran into a problem with my set up, it seems to me that only result of last iteratation is conciderd. And I need to use results of all previous iteration. I did choose “merge all iterations” - doesn't help.

I will be gratefull for any suggestion. My setup and the result I'm getting is on attached images.
