What's the correct way of unwrapping a trapezoid onto a brick texture without distortion? (and only one seam)

This is obviously the wrong way. Just to illustrate the problem: Like this the texture would be distorted on all 4 faces.

Also, if that is not what you wanted, try the cube projection unwrap method.
>>
It's not possible to unwrap with only one seam
>>
you can easily project paint these parts without unwrapping on image like a savage
>>
projective texture mapping is a solution.
>>
>>619829
would it even look real, i mean the brick layout to get that shape, i don't think you could do it with a texture
>>
OP has made something in Blender. It's not supposed to look real or good.
>>
>>619924
This. It would look as bad and be as impractical in reality as you might expect, so if it looks bad in 3D, it's not your fault as much as the fact that you're attempting it.
Such an object should look like a stair-step, with each row of bricks being upright, but gradually narrowing towards the top.
>>
>>619924
Real masonry is perfectly capable of doing this for thousands of years. You just have to shape individual bricks for the slopes/corners.

It works in reality, but case-dependent

>>619938
In rl, anon...obviously not in your 3D model.
>>
>>619937
The thing is that in your examples it's not bad because 1. They only slope on one axis, which is much easier to make 2. The bricks are still upright in the left picture, and 3. In the right picture there is a clear separatation in the brickwork as you might expect on an arch, which is a valid way to make bricks slope.
These are all ways of solving the problem, just not the one OP wants to solve, if they simply expect the unwrap to do all the work for them.
>>
>>619934
technically you can just cut the bricks into a slope, ending up with what OP is going for.
It's not common but it works.
>>
>>619977
It's not common because it's stupid and stupid expensive.
>>
>>619983
What do you know about masonry, 3D pleb
>>
You could try using 3d textures and/or AI but that isn't an unwrapping problem.

Otherwise, this assignment is impossible since surfaces in 2 dimensions don't just project unto surfaces in 3 dimensions without distortion.

I wish there was some mathematical proof to demonstrate this.
>>
>>620031
Triangle inequality maybe?
>>
>>619829
jaysus, stop unwrapping already

substance painter exist for a reason
>>
>>619829
not only impossible but also meaningless

Aye, it exists for the reason to be uninstalled and replaced by Mari

It's good to see that you are growing. I'm proud of you.

hot shit just project from view at the correct angel of the brick texture. so like just hit fucking go to the x,y,z axis grab the faces that "point" that way and unwrap via project from view. shit you could probably get away with stacking your textures if you didn't give a shit.

I like this style. We need more eXtreme tutorials.

unwrap before scaling the top edge.
>>
>>619829
unwrap the faces one at a time, line them up, and adjust the vertices (the top ones preferably) on each end equally to close the gap. your unwrap will be straight so you can project any material onto it instead of making a special texture map that follows weird directions or seams if you unwrap it any other way like this >>619832
>>
or just torrent xrayunwrap or something if you dont want to do any manual labor

What do you think happens when you take a square with a texture mapped to it, then scale down one edge, anon?

you get smaller bricks.
everybody knows that.

How's the new UI as an old user? I've gotten used to THE OLD WAYS and haven't updated since 2.78, I'm pretty interested in the new real time viewport thing but not really enough to learn a new UI right now
