r3yburn Posted December 28, 2020 Share Posted December 28, 2020 (edited) I am moving the position of the billowy smoke until it almost hits the ground however it doesnt collide with the ground entirely - I have played around with grid1>collisions>RDB Solver>Volume. The collision guide seems fine, the blue outline fits the ground. Can somebody please help me? volume_issue.hip Edited December 28, 2020 by r3yburn Quote Link to comment Share on other sites More sharing options...
ryew Posted December 30, 2020 Share Posted December 30, 2020 In your Static Object DOP, switch the Mode in your Collisions->Volume tab to "Volume Sample" instead of "Implicit Box". You're already calculating the VDB it's using for Proxy Volume and the Division Size matches your VDB, so just let it use that and it should be okay Quote Link to comment Share on other sites More sharing options...
