Carlosan Posted September 28, 2021 Share Posted September 28, 2021 Starting from 3DCoat 2021.53 the RGB cavity was introduced as the default calculation method in Texturing. This is a very significant feature for the PBR Painting over the Texture/Mesh. The reference model is XTZ DT-20 tractor, thanks to the manufacturer for your kind permission to use it ! 1 Quote Link to comment Share on other sites More sharing options...
Carlosan Posted September 28, 2021 Author Share Posted September 28, 2021 The video demonstrate how the improved cavity technology works. This is improved technology already called the RGB cavity. First you need to make sure that the RGB cavity version is enabled, to do this go to the Edit >Preferences go to the Tools section and select use RGB cavity as the default cavity calculation method. After enabling the function go to the Texture Menu then select the Calculate Curvature option. In order of the Calculation to be make you need to wait a bit. Now we can see how a Cavity map (RGB) appeared in the layers. - We see that in the new technology the map looks like a lot of color The map must be closed by default now let's create smart material to see how it works. - First you need to add Conditions to Degree value (more on convex like example) to see "vase" options. - Focus on a new edit icon -it looks like a vase-, this was added and did not exist before and it is with the spin edges that the update function is configured. It is the additional cavity width: The 0 value means that the cavity is taken from the materials settings as-is. Values less mean sharper cavity, more than 0.5 - widening of the cavity. Or course you need a RGB cavity layer in the scene to vary the cavity width. It works only on such conditions: more on concave, more on convex, less on concave, less on convex, more or flat and more on curved (you can use any of these modes) - The new parameter is responsible for the radius cavity. It is also affected by degree and contrast adjustments. 1 Quote Link to comment Share on other sites More sharing options...
Member GMG3D Posted July 19, 2022 Member Share Posted July 19, 2022 When I create a new Smart Material after doing all of this, I do not see the new Edit Icon 'Vase' option. Not sure what I'm doing wrong. Using 3D Coat 2022.29. Quote Link to comment Share on other sites More sharing options...
Carlosan Posted July 19, 2022 Author Share Posted July 19, 2022 Hi Did you do this step ? First you need to make sure that the RGB cavity version is enabled, to do this go to the Edit >Preferences go to the Tools section and select use RGB cavity as the default cavity calculation method.

Member GMG3D Posted July 19, 2022 Member Share Posted July 19, 2022 Yes I did for sure. It was already checked by default. I might try to update to the latest release today and see if it's still happening. 1 Quote Link to comment Share on other sites More sharing options...
Member GMG3D Posted July 25, 2022 Member Share Posted July 25, 2022 I have updated to the latest version, but still do not see this 'vase' option to adjust the cavity depths after generating the RGB Cavity map. I outlined the area in red. I'm not sure if I'm missing a step when creating a new smart material, but it's not there for me. This model is not unwrapped, I'm vertex painting this sculpt in surface mode, not sure if that has anything to do with it? 1 Quote Link to comment Share on other sites More sharing options...
Carlosan Posted July 25, 2022 Author Share Posted July 25, 2022 Add conditions to Degree value (more on concave like example) to see "vase" options. 1 Quote Link to comment Share on other sites More sharing options...
