If you want the smoke to interact with objects in your scene, for example, a naked female is lying down and you want the smoke to fall on her body and caress it without actually clipping through her body, then you will have to simulate this for yourself in Blender - it should not be too difficult if you have some experience in Blender (export your figure to Blender and use it in the fluid simulation as a collision object). If you would like more variations of smoke for your scene, but can't be bothered to make it for yourself in Blender, then try contacting me. ).ĥ) increase the Density Multiplier setting and alter the colors (Scattering Multiplier, Absorption Multiplier) to your taste.Ħ) with the domain cube selected and in the Parameters tab, increase the scaling (I used 2000% in the promo shot), rotate (I rotated X -90 in the promo shot), and place your smoke waterfall. Then come out of Joint Editor mode.ģ) with the domain cube selected, open the Surfaces tab, select its default surface, and apply the Daz Volume shader to it (mine is in My DAZ 3D Library > Shader Presets > Iray > Daz Volume > Simple OpenVDB MDL Volume).Ĥ) still in the Surfaces tab, under Volume File browse to the location of these files and select the corresponding VDB file (i.e. So, for example, to use the volume, first import Ģ) with the domain cube selected in the scene, activate the Joint Editor Tool, and in the Tool Settings tab set the XYZ for the Center Point to 0 (I also set the XY for the End Point to 0 although this might not be necessary). You will get a pathetically tiny box but don't worry - you can scale it up and rotate it later. Use the default import settings (scale 100%, Axis Conversion XYZ). For this reason I have made domain cubes (obj files) for use in Daz.ġ) in your Daz scene import one of the OBJ domain cubes. Implementation in Daz 4.20 is a bit tricky due to scaling and rotation, and mostly positioning of the origin point. The inspiration for these simulations came from Aria Faith Jones's youtube [ They can presumably be used in any 3D software which supports OpenVDB. This edition includes 11 frames from 3 waterfall simulations. These smoke waterfall VDB volume files were produced by Thrwm using Blender 2.93.5 fluid simulation.
