I get small graphic issues sometimes on the button icons. Buttons on the parameters and some other buttons on the UI gets distorted with overlay of colorful noisy pattern and becomes not readable. It doesnt happen often and not a big issue but annoying one. I am not sure if my gpu is dying or not. I didnt have this with 16.04 and 14.04. Also I had same issue with Mint 18.04 "sara". Also I have experience some crashes when computer went down to sleep mode.

Thanks Dominik for the answer! I never thought about the step rate and I was hitting my head against the wall all day. However same setup in SHOP context doesn't seem to work in MAT. I uploaded the hip file if you are interested to check. Thanks again, Alican volumeProcedural.hipnc

I am doing pcopen in cvex to to render points as volume but for some reason I am not able to scale the density as much as I want. It looks like it is clamping the density values and doesn't allow me to go higher. When I use smaller IFD bounds this problem fixes itself but also it cuts my overall object. Also vex volume procedural doesn't seem to work with new mat context. Thanks for the solutions, Alican

Creating a dot node shouldn't force to cook the chain.

Hi, I am making a digital asset and it's simply a force effecting the vel field. I want to put a control field option but I couldn't figure out how could I bind a user input field to a constant variable in code. When I look at a similar asset like gas disturbance, they are made with VOPs and I kind of got it. I would appreciate if you could help me with the wrangle option. Thanks!

Hi fortysix, the hip file is just a prototype that works with the embedded model. If you want to use it with another model there is bit of prep work to be done. There is a nice example Alexander Weide did by using this hip file but yeah its not a plug your model and thats it type of solution. You need to dig it in a little bit unfortunately. Also some parts might have been over complicated than it should...

Yeah I thought so but if I just want it to stick and slide on the surface it becomes much harder to achieve by adding extra velocity.

I am making a smoke sim from the surface of a deforming object. And I want to use that object as a collision. But the collision field is eating my density field and I get a wierd result, density is disappearing when colliding. Is there any solution to this? Thank you, Alican

I think it is just "Single Pass" option is ticked in the final for each loop. I can see it from the image "Gather: 73" it writes next the node. Just turn off the single pass option and it will generate every iteration but it will take some time around 30 seconds to minute. It might be heavy for your viewport so it is best to put the render flag to that node and visibility to a lighter node for the viewport.

Hey bretik, at some point in the network I just transfer the color from uv's to points. You might need to activate using point colors in the shader to get the colors and also check if the path to the texture is correct in your hip file=) And in your second image it seems there is only one iteration of the for loop happening. Cheers!

Hi bretik, I didn't include any of the the rendering or shading nodes. But it is very straightforward. I rendered the whole geometry as curves with width attribute and the render flag is set to the last node of the chain. Some things might change depending on which render engine you want use. That was it basically.

Instead of using geoself(), this should work detail(opinputpath(".",0), "resample_count", 0)

Thanks! It would be great to see if you come up with a tool. I hope the hip file helps. Cheers!

Hi all, I had been doing a rnd project on how to generate knitted garments in Houdini lately. And one my inspiration was from a project which was done by Psyop using Fabric engine and the other one is done by my friend Burak Demirci. Here are the links of them. http://fabricengine.com/case-studies/psyop-part-2/ https://www.artstation.com/artist/burakdemirci Some people asked to share my hip file and I was going to do it sooner but things were little busy for me. Here it is, I also put some sticky notes to explain the process better, hope it helps. Also this hip file is the identical file of the one that I created this video except the rendering nodes https://vimeo.com/163676773 .I think there are still some things that can be improved and maybe done in a better way. I would love to see people developing this system further. Cheers! Alican Görgeç knitRnD.zip

I am trying to make a scroll roll deformer like this one Do you have any suggestions how I can do the similar effect. Cheers!
