Member Hickz Posted February 21, 2022 Member Report Share Posted February 21, 2022 (edited) I'm having issues while painting 100% roughness over a layer with any roughness in stack. Look at the video for a better explanation. This doesnt happen if i drawa roughness along with color. In the video you will also see that the roughness you paint will disappear once you hide the layer beneath. This whole thing might be connected to issues mentioned in these topics: Edited February 21, 2022 by Hickz Quote Link to comment Share on other sites More sharing options...
Carlosan Posted February 21, 2022 Report Share Posted February 21, 2022 Hi apparently you can't draw roughness without color?, yes you cant i was testing 2022.06, but cant replicate sorry 2022.06 Quote Link to comment Share on other sites More sharing options...

Member Hickz Posted February 21, 2022 Author Member Report Share Posted February 21, 2022 I don't really know why, but i can paint roughness without color/metalness with values other than 100%. For example, 95% will work properly. 1 Quote Link to comment Share on other sites More sharing options...
Advanced Member Yousung Posted February 22, 2022 Advanced Member Report Share Posted February 22, 2022 (edited) test progress Yes, I've also seen this happen. If it's a bug, it should be fixed, if not, it needs improvement. It's quite confusing. Why do we need to enable the Color Channel to paint Rough, Metal? If you want to express something like fingerprint marks on the surface of an object, you don't need this color value. Just enable Roughness and you should be able to paint. Edit 1) Oh, I didn't see the last post by Hickz @Carlosan Yes this definitely seems to be a bug. Painting in this way preserves the layer and doesn't mosaic (break).

Advanced Member Yousung Posted February 22, 2022 Advanced Member Report Share Posted February 22, 2022 Perform 'Reset Settings' - It does not solve the problem. As an additional explanation in the comment above, the mosaic (broken) is something like this. As Hickz explained, if I paint anything other than 100% (tested at 99%), it works fine.

Advanced Member Yousung Posted February 22, 2022 Advanced Member Report Share Posted February 22, 2022 This is a video that implemented Hickz's problem from the beginning. Tested in 2022.07 version. As a result of testing so far, it seems that this problem only occurs under certain conditions. 1. Test on a new, empty layer 2. Turn off Color Channel and Depth Channel. 3. Set the Roughness value to 100. 4. Set the Metalness value to 0. 2 Quote Link to comment Share on other sites More sharing options...
Member Hickz Posted February 22, 2022 Author Member Report Share Posted February 22, 2022 Another thing i noticed is that while painting roughness, the pen pressure doesn't affect the value of the roughness, but the opacity is affected. On the other hand, i'm not even sure how to implement it, for example: should smaller roughness values be applied when you press lightly and bigger values when you press firmly? How is that gonna play along with opacity pen pressure? Quote Link to comment Share on other sites More sharing options...

The Opacity values of Roughness and Metalness should be increased to the maximum.It works differently from Opacity of Color. When painting with a Roughness of 38%, no matter how high the pen pressure is applied, only 38% is achieved. In the case of Color, the colors are superimposed and strong, but Rough/Metal is not. Experimentally, after painting with the Roughness value set to a high value (I will take an example of 99% because there is a bug now), if I set the Roughness value to 50% and paint again, you can see that the Roughness value is changed to 50%. The same goes for Substance Painter. Quote Link to comment Share on other sites More sharing options...
Advanced Member Yousung Posted February 23, 2022 Advanced Member Report Share Posted February 23, 2022 (edited) Please try this instead. This is probably the way you want. Opacity - 38% Roughness - 99% It says 'Color Opacity' in the description, but it seems to work like 'Master Opacity'.

What i meant is that there is no need to have the pen pressure switch for roughness then to begin with, if only the roughness that is set in the slider is gonna be applied despite whatever pressure you use, since only master opacity is considered.
