I use albedoColor as background color. I find out the albedoTexture (an image) will blend with albedoColor and the image color will faint a little bit. In extreme cases: when the albedoColor is 1, plain black, the albedoTexture wont’ show up at all. 2, plain white, the albedoTexture shows up wit…

I forgot to answer and say thanks in that topic after “solving” my problem. Comment from @PatrickRyan is good description. I actually even managed to make it work with custom shader: At first glance, I think you would need a custom shader using a node material which uses an alpha channel in your a…

Hey! can you provide a repro so we can have a look (in the Playground)

this is the expected behavior , albedo color acts as a tint for the albedo texture , when you have a texture. If you dont want any tinting, just make the albedo color pure white when using a texture.

yep, I think so. it’s designed in this way. just wonder if there is a way to make a colorful background but won’t blend with texture? I’ll try to create a miminal playground.

[image] jesse: a colorful background but won’t blend with texture First of all, there’s always a way. Given the tons of properties and all the channels you have in a PBR material, there’s a lot you can play with, twist and tweak and disrupt :grin: But then, you can’t go against the laws (of …

I think I should give up on this. 3d is not my field. I’ll do the background thing outside babylonjs. a canvas filled with expected background color, add new images to the canvas, then use the canvas as htmlelementtexture.

[image] jesse: I’ll do the background thing outside babylonjs. May be misunderstanding here. This is not just a 3D thing. It’s the same with 2D (except for the properties you can add to a PBR material). If you do it in 2D you can easily get the same in 3D. May be you should just share a scree…

[image] the front side (the cat image) can be customized with user’s image. but the background must be pink color. the background color is easily done in canvas but our business is sorta complex, so I’m trying to achieve the background color thing in babylonjs.

thanks, that clarifies it (sort of). I would have one more question: Does the color of the bag (‘the background’) slightly ‘tint’ the cat image? I suppose so. Looks like you are trying to create a plateform that let’s you personalize items (and then, deliver the real thing, is it?) So, this would b…

the real product has slight color difference with canvas texture. it’s not just slightly “tint” with babylonjs albedoColor and albedoTexture. we have a plain black variant for the pink box I attached in the previous reply, if I set the albedoColor to black then the albedoTexture wont’ show up at a…

So, you are actually doing the real product? And when you say ‘canvas’ you are refering to this thingy that makes you think you can create proper design and html sites in two clicks :grin: is it? Ok, well, first things first: this blending method of source over is never going to make for a proper s…
