Thanks a lot for your support! Yes, initial 10-15 days were quite hard and difficult. Now it's becoming easier. Please share the link of their channel. I can't seem to find it. A quick google search gave me this...

I'm trying to make a volume that dissolves along the x axis like this. But my volume is getting dissolved inwards like this.. What should I do? The houdini file can be downloaded from here. https://www.dropbox.com/s/3yw4x4kdnh50i56/VOL DISPLACEWORK.hip?dl=0

Actually I have that course. I made one geometry also from that course in which you helped me a lot here. I reached till video number 12 and felt that although they briefly explained the principles of VDB, volumes and voxels, they don't state reasons of why they are doing a particular step in their workflow. The pace is also quite fast and I have to rewind multiple times in order to follow up the exact process they're doing. I learnt the basics of Houdini from Rohan Dalvi's videos which he explains very well at an easy to follow pace. However I still haven't yet found a tutorial in which all the reasons for steps in designing volumes are also being explained. The best that I've found are TIMJ's ones. He mostly explains the logic behind all the steps that he does, but sometimes he misses.

Thanks a lot! That fixed it!. The tutorial is explaining the steps but not explaining the reasons of the node connections being used in the volume vop. Can you please suggest some tutorials which explain exactly why the nodes are used in this particular sequence ?

I'm trying to achieve an advect growth which should look like this. But it's looking like this. Please help in resolving. I'm following this tutorial. Here's my file. Houdini Session - VDB Advect Growth_forum.hip

Thanks. Their server is down though. Maybe I should try again tomorrow.

Ahh! I see!. Becoming proficient at using Houdini requires eagle eyes seriously! So many details. So many buttons.

I want to download Houdini 17.5.229. Unfortunately it's not showing up on the official downloads page here. https://www.sidefx.com/download/daily-builds/ Any alternative source where I can download this build?

Thanks a lot for pointing out my mistakes. Before looking at your reply, I developed the script from scratch twice and it eventually worked in the second attempt . I also accidentally forgot to name the bind as 'vel' of volume vop in accordance with the vdb1. Your script is interesting too. It has a different style of growth. One thing I can't understand is the bind type is still float (which should be vector) in my enclosed file, yet the growth is functioning. Why does the volume still grow fine? I watched the video too. They also have kept it as float. ADDING FORCES_SECOND ATTEMPT - Copy.hip

Thanks for the links. Really interesting geometry. I can't seem to figure out the one I shared in the original post. How can I grow the volume uniformly in all directions on the icosahedron?

I don't have the project files. Otherwise I'd have figured out the method till now. I followed these three videos. The final one is in the one which they've done the majority of growth settings. https://drive.google.com/file/d/18N74Bm9JDYMHubSgYWgQVxFJOAs9mbPq/view?usp=sharing https://drive.google.com/file/d/19E1piUUh4oPyqtiUVuksyQN6v10KW87h/view?usp=sharing https://drive.google.com/file/d/1jz6jHadaIdweX7NH8E0u8xEj3VP-cejf/view?usp=sharing

Thanks a lot. I studied the script that you sent me and could only figure out changes in only two places. 1. The bounding box sizes. 2. The graphs. What other changes have you made? I applied the above changes that you did but all I could get was a blank volume in the simulation. Moreover, how to grow the volume uniformly in all directions? Sell by NTF? I don't understand. What is NTF?

I'm not getting much growth except for this. I'm watching video 11 Adding Forces To Our Solver from Entagma's Volumes 101 course. I played with noise setting but not something significant I'd get. One more thing. Reducing the voxel size is not improving the quality of the mesh. What is that so? Play (1).hiplc

I'm trying to achieve noise based growth in an icosahedron which should look like this. However, instead of growing, my volume begins to shrink instead. Please advise. volume growth question.hip

Thanks sir. I'll surely go through the video.
