No FX blend mode?

[Bit Disappointed]

I haven't fiddled with it long enough to have a definitive conclusion, but isn't it my understanding that we can't control which blend mode FX is rendered with?

I work with very accurate colours in some of my elements, and I can see on greyscale elements in particular that 3D FX changes the colour towards blue. At least that's what happens in my current design. It's frustrating that the colours shift when I put FX on some elements as the last modification. 

I would really like to be able to set the blend mode for FX to luminosity in this case. Can you already do that - and don't I have a point?

Only 3 out of 10 FX have no blend mode.

Please provide an example Affinity document with the problem so we can investigate and, hopefully, offer solutions.

Haha you are right - I completely overlooked that. Need more quality sleep. But no choice on 3D. 😞

Thx. Try disabling 3D FX on the layer metal - then enabling it:

Desperate for progress I just switched to bevel/emboss instead that in this specific case probably is the right choice. Delivers a similar effect without the colour cast which is interesting.

I don't really know what it is you are aiming at colour wise. But I did notice that the document you uploaded is CMYK. Have you tried changing to RGB? It makes quite a difference.

It's a metal plate that is classic metal gray, which should remain metal gray. But you are actually right that it's a CMYK side effect, I just have no idea if it's an expected color shift. I assume that the gray tones should be able to be maintained if there was an option to set the 3D FX blend mode to luminosity.

Although it's probably not exactly what you need, you can try inserting the Metal layer into the Group, copy/paste the fx to the Group + set the blending mode (Saturation works best for me), and then disable the fx for the Metal layer.
