1. ## Sand simulation using the Guided Ocean layer tool

Hello Houdini community, I was wondering if anyone had had the idea of using the new oceans tools to do sand effects. I am trying to figureout the best way to set up an object in a vast desert that is rising up through the sand. A number of years ago I took Spencer Leuders class on CG workshops using fluids and one of his classes used vops to manipulate the fluid to behave like sand. My thought is to take a similar approach but do it to a flip tank with an object rising from underneath the sand. This is how I think it should be setup, but don’t know if it’s the best way to do it. I would love any tips. Thank you guys for your time. Object rising.mov Ocean_Sand_v01.hip
2. ## Sand shader (For Geometry not particles)

Hello all, I am trying to figure out how to create a procedural shader that looks like sand (Applied to geometry, not particles) Are there any posts that you guys can point me to that would help me know where to start? Thank you Sand shader for dunes_v01.hip
3. ## changing the normal directions of a shape

This is perfect. Thank you again for this.
4. ## changing the normal directions of a shape

I Think I figured it out I used your concept and applyed the normals that I created with the attribute transfer sop Thanks for your help!
5. ## changing the normal directions of a shape

Thanks f1480187, That's kind of what I was going for, but along the lines of the following image.
6. ## changing the normal directions of a shape

Hello, I am trying to figure out how to achieve making normal rotating much like exsample_1 but around an entire shape like in examples 2 and 3. Any input on options would be great. Thanks in advance. Normal Directions With Geometry.hip
7. ## Offset random voronoi pieces in the x axis

Thank you Tomas! This is what I was looking for.
8. ## Offset random voronoi pieces in the x axis

Hey Guys, I posted last week about how to offset primitives randomly in the x axis. http://forums.odforce.net/topic/25619-offset-random-primitives-in-the-x-axis/ Now I am trying to do the same effect but with solid objects, or fractured geometry. I have it working but the geo is being sheared as it is moving. I am wanting the geo to not morph, just move. any suggestions would be great. Thanks. Offset_geo_chunks_Random_x.hip
9. ## Offset random primitives in the x axis

Thanks guys. This is extremely helpful.
10. ## Offset random primitives in the x axis

Hello, I'm trying to offset random primitives along the x axis of a object. I have a setup of how to do it in a For each loop, but whats not as clear is how to do it in vops. Is there a way to separate the P attribute in VOPS to only effect one axis? Offset_Random_x.hip
11. ## For Each Loop to effect size

Thanks Jrockstad This helps alot! Where did you pick this up? I've found plenty of info on how to use the copy sop with stamp functions but not doing this within a Foreach loop. Thanks again.
12. ## For Each Loop to effect size

That would be great. Thanks jrockstad!
13. ## For Each Loop to effect size

Hello I am trying to effect the size of each piece of geo in the following image. I want each piece to be a random size, I feel like I'm almost there but am missing a bit of Hscript to do it. Any input would be great. Thanks in advance. For_each_Size.hip
14. ## RBD object to Cloth sim

I may have figured it out. Here is the latest on what I'm trying to do. Got to figure out the twitching now. Any comments would be appreciated. RBD_object_To_Cloth_v2.mov Attach_RDB_to_Cloth_v1.3.hip
15. ## RBD object to Cloth sim

Hello Houdini users, I am trying to figure out how to attach a RBD object to a cloth sim. I am wanting to attach the object to the cloth so that it is weighing it down as the cloth rises. Hip and mp4 attached. Thanks for any input. Attach_RBD_to_Cloth.hip RBD_object_To_Cloth.mov
