Thanks Mr. Toadstorm... I think this could do the trick for what I'm doing!

I'm trying to create an automated ball roll... I found some helpful tips online but am still struggling to get it to roll correctly. Attached is what I started... I'm wondering if there is an easier way to rig this? Maybe through a sop solver. Anyways any help is much appreciated! Thanks, AutoRoll01.hip

In a wrangle write: v@ndcP= toNDC(chs("cam"),v@P); float padding = chf("padding"); float nearclip = chf("nearclip"); if(v@ndcP.x > (1 + padding) || v@ndcP.x < (0 - padding) || v@ndcP.y > (1 + padding) || v@ndcpos12321.y < (0 - padding) || -v@ndcP.z < nearclip){ removepoint(0,@ptnum); } click on the spare parameters and add the camera you wanna add.

If your want a differential Growth effect there a a huge thread on it. Hope this helps.

Hello have you taken a look at this?

This should help too.

Happy Friday, I'm trying to replicate this long exposure effect. It was done by taking a series of long exposure shots then re composited in post. I've gotten pretty close by doing a trail and forcing velocity over them to create the blurriness but it's not close enough... I was wondering if anyone had any good ideas or a closer solve for this problem. Any help is appreciated! Thanks,

I wondering if this is even possible? I'm animating points through a solver and then turning them into vdb's. I want to apply a random color on each particle. Everything seams to work until I convert to polygons. I tried to apply an attribute transfer after the convert but as you can see in the attached image the scale is off? If anyone can provide further assistance... It would be greatly appreciated! (I also attached a reduced file since I cannot send the actual scene) Thanks, vdb_HelpMe.01.hip

Hey all, I got super excited on this image and started to make something based on it And now I'm reaching out for some guidance. Attached is where I was heading... still not getting the nice symmetry and variety that the image has. Any help would be appreciated thanks! cube_v001.hipnc

Thank you this is great! -

It looks like this method only works when you do it directly from a prim. If you scatter points or do it from the ray it doesn't work. -

I'm trying to delete points bases on the camera's origin. I have a vex script that was calculating the visibility: vector camera_dir = point(1,"P",1) - point(1,"P",0); f@vis = dot(@N,camera_dir); the problem is that it's based off of having two points from a ray sop. Can I just do it based off the camera origin itself? Any help would be amazing! Thanks, camOrigin01_v001.hip
