Hi Luiz

I copied the Fluid Vertex Animation UE4 Code, from the HDA in the dropbox download from above, into a material in UE4 and got the results below. It looks like what I had earlier.

I have a similar issue to the first picture Ilya posted. Below is a picture of the mesh that is exported and the material setup. The vertices do not seem to be attached and the material makes everything shake a little bit.

I am not sure which node I am suppose to be exporting in Houdini but I tried every node in /obj and got similar results.

Thank you so much for the fast and amazing work you are putting into this. If you could send me the HDA that would be awesome. I will also try the scaling down the mesh and simulation when I get home from work.

Thank you for the quick response.

I have tried the Fluid technique and received an error saying I had insufficient memory. I have tried it with very few particles and low texture output resolution but still got the same error.

My system specs are:
Intel 15-3570K
Nvidia GTX 660ti
8GB of RAM

I have attached a zip file with the Houdini file and textures you need for it.

Hi all,

I have a FLIP simulation on a planet I made and would like to get this going in UE4. I export it with the vertex_animation_textures node in Houdini 16 and that gives me a normal exr, position exr and a mesh. I then import those into UE4 and copy and paste the Soft Vertex Animation code into a UE4 material and assign the textures. When I finish all of that the animation completely breaks.

I attached 3 pictures which show the mesh with no material (water_01), the mesh with the material (water_02) and the material network (water_03). I have tried using a number of different nodes in my network as the Export Node with similar results. I must be doing something wrong but I am not sure what. I have also attached my hiplc file. I also have Houdini Engine installed in UE4.

An ideas?

I have also been trying to do this. If anyone has a solution I would love to know it.

Sorry about that. Thank you for pointing it out. I have edited the original post to include the attachments.

Hi all,

I am new to Houdini so my apologies if this is if I am missing something simple here. I have a sphere that I used an Attribute VOP to displace points and add hills. I want to be able to export a heightmap based on the displacement.

I think to do this I would have to somehow export the value from my Displace Along Normal node but I do not know how to do this. I tried a Point Cloud Export but that does not seem to be right.

I have added a pic of my original sphere, the displaced sphere and the network. I have also uploaded my .hiplc if that helps anyone.

Thank you,

Clint
