For sure, I was able to get away with turning on the sample lock for my render.

hello, I am trying to use the subtract collision volumes on the particle fluid surface node to make my water inside a sphere fit inside. So I converted a sphere to a sdf and used that as the collision. As you can see in the second photo, it deleted the inside, but I want everything on the outside deleted. So I attached a volume wrangle inverting the sdf, but that still didnt work. I am confused why inverting the sdf would not work. thanks in advance

Thanks, for some reason searching these forums can be difficult : )

Hello, I cant figure out how to render this shot without lots of noise. I am getting ridiculously harsh noise from my hdri reflection off my objects. I turned on image planes to confirm the noise is happening in direct reflect. things I tried: 1. reflection quality-little to no difference 2. sampling quality on light-little to no difference 3. pixel samples- I cranked it all the way up to 10 and it looked better, but was still noisy and took way too long to render 4. noise level-little to no difference So what else can I try? The only thing I found that was viable was turning on sample lock so I dont need super high pixel samples, maybe I can add the noise back in post? Thanks in advance.

thats where I read, but I didnt seen any where to turn it off :(. Sometimes when I am inside like a building model, I have to change the focal length to navigate easier, but then this annoying screen comes up when you change the focal length with ctrl + right clk edit, I am trying to change the FOV but I dont want the screen window darkening everything

no one knows how to do this : ( seems like it would be a simple fix

Older versions of hou did not do this, but when you change the fov by hitting ctrl + right click, it brings up this annoying screen window. How do you turn it off? Thanks

In case anyone else needs to do this, I made a free hda to do this. you can add noise, rotate, scale and transform randomly!! and it is done all in /mat. Make sure to lay out uv's before using. The hda is included here or you can get it from the link in the video on youtube. example.hiplc uv_randomize_b.hdalc

Is that a render or viewport? I am doing a sim now, it flickers int he viewport with the volume visualization node, but the render is fine.

I figured out how to rotate them in sops, but I can't figure out how to do in in a material. The earlier example material was nice, but I don't want to create additional rows, I just want to rotate based on the center of the existing uvs.

Hello, I made this tutorial a while back, this might help you.

Hello I am starting to get into unreal engine. As a vfx artist, I am just looking at getting HDA's/terrains/effects in unreal engine. For such basic usage of unreal engine, would blue print projects offer enough functionality? Thanks

Hey! you'll be happy to know its really easy. Just drop a group delete. then choose delete unused groups and bingo, thats it.

Here is an example using curveu point attribute as a mask to limit noise. vdb_mask.hiplc

@karen its white because you are viewing the wrong pass. IF you look at my photo you have to view the right image plane. Open it in mplay and select diffcolor. you might need to save it as something other then jpeg for multiple channels. Just try by hitting render to mplay and to test it.
