Hi
I have fluid sim, that I would like to save as particles and then convert that to a surface and save that as an alembic. I have a manual setup at the moment. Where i save the particles in a DOP IO, come back when its done and then save as alembic but it would be great to have it automatically do this so that i can leave it overnight. with the rops I have been able to que them up but the alembic exporter dosent seem to have that option.
Thanks

Houdini Indie and Apprentice » Timeshift unable to read

Hi
I have been having this issue when using time shift not sure what I am missing. In this case its a fluid sim, I did a time shift its all working in the viewport but when I go to save the particles as a VDB it give me an error saying unable to read source and invalid file. However if I click back onthe node above ROP everything loads back again fine in the view port.
Thanks

hi
I am doing some particle work, and I would like to see the scene geometry as a guide in DOPS level, is there a way to do this. I thought the SOP guide node would do this but I am not getting anything from it.
Cheers

Hi,
I have seen a lot of posts about exporting PRTs from Houdini but what I would like to do is import them into Houdini as points is there a way to do this? I have some nebulas saved out in PRT format and I wanted to do some experiments in Houdini with them.
Thanks

Hi,
I am trying to calculate the y distance of a cached fluid sim in a tank. and I would like to have a color going from from black at the bottom and white at the top. The idea is to then use this in Mantra to drive the roughness of the transparency or the tint to create an ocean shader. I am trying to do this using a vopsop, I have tried various methods that other people have tried and I can only get it partially right. most of the time it seems to be calculating the distance from the center rather than the Y distance. In the file attached I get the gradient at an angle rather than straight up.
I am totally new to this and any help would be appreciated.
thank you

It was that preview button in the render view. I am not sure what its doing but its not working well on transparent objects. Back to the fun stuff.

I get the same issue with or without the caustics.
The HDRI is too big to attacg but its the same with any HDRI. I thought that was the issue at first.

Hey there,
I am new to houdini rendering, just got this simple test scene. As soon as I add transparency to the material I get a lot of noise. I have tried increasing the refraction,reflections and light samples. But all that does is increase the render time. There must be something simple I am missing regarding transparent objects because when i take the transparency off I get a good clean render pretty fast.
Adding the different passes it seems the reflection pass is the one with the noise.
Any advice would be appreciated.
Thanks!

Hi
I would like to do the same thing, but I am getting the seed change on every frame when i used the expression. Any thoughts on this?
