[Fixed] Brush size difference between Paint viewport and Texture Editor

[bokbok]

Having moved from using Substance Painter to 3Dcoat, there is something that keeps bothering me and I think I might be missing a setting somewhere. I've Googled this issue several times, but I can't seem to find anything about it. 
In Substance Painter whenever I'm using a brush, I had the choice to keep the Size Space at "object", "viewport" or "texture". This is particularly helpful when painting a lot directly on the mesh as well as on the unfolded texture. Now in 3Dcoat, whenever I am painting with a certain brush size in the "paint" 3D vieport and I move into the "Texture Editor", the brush is much smaller. I have to keep reajusting its size, so I was wondering if there was an option to keep the brush size at object space. Thank you!

I have the same question. 3DCoat Textura 2021.57

I have the same question. How is the brush size decided?

Hi Carlosan,

I've just recently downloaded Textura 2024.17.  I am still getting this issue, it has apparently not been fixed, and it is making it impossible for me to consider switching to Textura and paying money for the upgrade from 3dCoat4.

My brush radius in the projection painting viewport is consistent, yet as soon as I move my brush across multiple uv islands in the Texture Editor to begin additional painting there, the brush size adapts automatically to the size of the uv island. If I mouse over a large island, the brush radius gets bigger, and over very small islands, it becomes tiny, and impossible to use. It's an absurd feature/bug that is immensely frustrating and gets in the way of my workflow. I have to continuously adapt my brush radius to what it needs to be. 3dCoat4 did not do this.

When I am painting in a painting program, I never want the program to be making tool or brush decisions for me.

I have searched all over Textura for options to turn this off, and have not found anything, anywhere. Sleuthing like a detective for options and trying to figure out the bugs of 3d Coat is still honestly a nightmare even in the most recent software and versions. It's also frustrating to come to the forums looking for help, and to find a 'fixed solution' that is not a fix for my up to date version, nor an explanation for how it was fixed, or explanation on why the issue was occurring, and if there is a way to deal with it if someone is still having the bug. Transparency is really not present with 3d Coat support.

Hi

I was testing 3DCTextura 2024.18 and it is working as expected.

Please give a try

My radius is changing

I am lost, from my side it is working

what I miss ?

I find it difficult to answer. Same behavior in 3dcoat.

It is correct. The brush size corresponds to some radius in world space. But the UV density differs, so radius over UV differs to keep correspondence between world space radius and UV.

The sport in the 3D viewport and spot over UV will look similar; this is the purpose.

But why?

What if I don't want that? It actively makes texturing more difficult. It takes control of my texturing workspace out of my hands, out of the artist's control.

I DON'T want to have to adjust my brush size over and over again when I'm doing detailed painting on the texture editor. I use a graphics stylus, like I expect the majority of artist do, and changing brush size on the fly with a stylus is a time waster without a mouse scroll wheel, and 3d Coat's clunky brush size and opacity sliders. I often use a large soft brush over the texture editor for gradient and shading, and if my brush size is constantly shrinking and growing out of my control as I move around the texture map, it massively interferes with my workflow. And by the number of confused users here, they also don't see this as a beneficial feature, but as a frustrating bug.

I am a mobile artist. The models that I work on are often low poly, low resolution maps, and my uv space is extremely optimised. Sometimes I have to work across very small, tightly packed uv islands, and having my brush size shrinking and growing, shrinking and growing, everytime I go to do something on the texture editor, feels like a nightmare.

Previous versions of 3d Coat did not do this. You had the texture editor, and it worked perfectly, and you were able to control your brushsize, and your workflow, across the entire projection painting process. Control of the brush was left entirely in the hands of the artist. Imagine if in Photoshop the program decided what your brush size would be for you, based on the size of what you were working on? The fact that there isn't even an option to turn this off is crazy to me.

 

Because of this issue, I immediately uninstalled Textura, and did not buy the upgrade. I will not buy or upgrade to a new version of 3d Coat unless I know there is an option to turn this feature off. Any 'feature' that takes control of the process out of the hands of the artist is a waste of time to me.

I forwarded your request to dev team suggesting that they could add that option (select old or new style) to Preferences. 

In the meantime, if you prefer, you can use the previous version that served your work better.

Ok, implemented in the 20th build, there is a choice, use space-based radius or pixel-based one.
