3. ## Increment value by one on every frame

Thanks all for reply Both ways are working but my situation was different that i didn't describe properly.I want to increment by one on every frame but for different point number on different frame. Like if random points are turning red on different frame number so increment should start from that frame number for that particular point. I solve this using wrangle in solver node. I want to know any other way also .
4. ## Increment value by one on every frame

Hello I want to increment value by one on every frame after frame no, x (for example 50 frame no.). I tried doing this in wrangle its not working. it stay at one after frame 50.. Its like houdini is reading this script independent on every frame. Its working in solver node actually but i want to know any other way on sop level. i tried this .. if(@Frame>50) i@a+=1; Please share with me if you have any way out. Thank you
5. ## How to store all primitive number in array using VEX

Thanks F1 its working perfect.
6. ## How to store all primitive number in array using VEX

Hello I want to ask one quick question. How to store all primitive number in array using VEX. I am writing int nearpts[] = nearpoints(@OpInput1, point(1,"P",0), 20); to store points in array. Now i want to store prim num. I connected grid on 1st input and one centre point on 2nd input to use this one. If you have other way to store points tell me that also. Thank you

8. ## RBD hitnum not working

Thanks Martin for reply and giving me example file. I am facing problem in rbd .Particle are working fine. In RBD hitnum attribute is not changing. It remain zero after collision.
9. ## RBD hitnum not working

Sorry i can't attach scene file. I get hitnum attribute from pop collision detect in DOPs but it not changing value after collision. I want to use that attribute inside DOps in pop wrangle to stop small rbd pieces after couple of bounce.
10. ## RBD hitnum not working

Hi guys, I just want to ask one quick question. I am using bullet solver and want to count hit value of pieces with collision geomectory. I tried pop collision detect also but its not working on rbd. thanks
11. ## RBD constraint come back after removing

Hi Tim, My problem has been solved. I just did what Thomas said in 1st point Or you can keep that 1 but make sure that parameter color should stay red.
12. ## RBD constraint come back after removing

Hi guys I just want to ask two quick questions. 1. I don't want glue constraint come back after removing, in my case it come back after removing and it make fracture pieces not fall/break properly. 2. I also want to control the bounce of fracture pieces ,they keeps on bouncing. I wonder if there is any method to deactivate sim per pieces. Thank you in advance
13. ## Cracks are visible in render before it happen

Hi Joe Long, Thanks you so much. This is exactly what i want to do. I was stuck in this. Thank you

Hi Joe Long I tried what you told me..but not working properly. Perhaps i did it wrong way. I wonder if you could tell me how to do that or show me in my given file above. Thank You
15. ## Cracks are visible in render before it happen

Hi Guilherme Casagrandi You render this without displacement material .Try render with material i made (material name displacement_2 for inner displacement and displacement _3 for outer displacement).
