Hello,
I’ve got some diffilculties with the map density apply to scatter. How it is working ? and what are the parameter to use for the map ? please
Dear @Blizard , hello.
I will share a little trick that could help you to understand how the Density map is applied to Scatter.
After choosing Scatter Guests and host please follow these steps:
1. Create a new Generic material (named here Test_Scatter) and apply the desired for Scatter density map into the Diffuse channel (Paste it as Instance), see here. Used in the example is V-Ray Checker Texture.
2. Apply Test_Scatter material to the host geometry (it will be temporary until you receive the visual understanding and the wanted effect) and perform a test render, see here.
3. Go to Test_Scatter > Diffuse slot (= Scatter density map) > Texture Placement and change Repeat U/V values. Perform another render to see the result, see here.
4. If you need, tweak other Scatter parameters as well. For example Seed, see here.
5. Replace Test_Scatter material with another one more suitable for your final rendering, see here.
Please perform the described above and contact us with feedback.
Thanks in advance.
Best regards,
TS
