Warp group problems

[PierMax]

Hi, Warp group (perspective) make indesiderabile deformations, thanks 

 

[GarryP]

I can see the problem where the right-hand arrow is pointing to but I can’t see the problem that the other two arrows are pointing to (I can also see a problem at the top-left where the cog tooth doesn’t quite reach the circle). More detail in the problem description may be needed.

I have not been able to replicate the problem that I can see in your screen-grab with my own version of the design,

Can you upload your document so we can try and see if we can reproduce the problems ourselves? (Otherwise we are just trying random stuff in the hope that we can get the same thing happening.)

Thanks for sharing the document.

I can’t see a Warp Group layer in there (but I might have missed it).

I stripped out all of the extraneous layers and tried adding a Perspective Warp Group to the ‘flat cog design’ and it seems to be working okay for me.

To check to see what’s happening with the Warp Group functionality we need to see the document with the Warp Group layer in it.

I did notice that your ‘red perspective rectangle’ doesn’t match the equivalent ‘black perspective rectangle’ because the sides of the ‘black perspective rectangle’ are curved – see green markers in attached screen-grab – but I don’t know how it got like that as I don’t have the Warp Group to look at and I don’t know what’s happened to it since then.

If you don't see the warp groups it's probably because when I did it yesterday I pressed the bake button. I added the red lines separately so you could notice the difference.

That’s what I guessed could have happened.

Unfortunately, without being able to see the result of the Warp Group directly, I can’t judge what could have gone wrong.

For example, the warping might have worked exactly as it should have but the subsequent baking could have introduced the problem you’re seeing.

We’re seeing the result of two (or maybe more) actions and trying to figure out which individual action caused the eventual result without being able to see the intermediate results – like doing some calculations and just looking at the final answer; it’s difficult (if not impossible) to know what the original numbers were, what the operations were, or in which order the calculations were done.

If you can reproduce the problem before you bake the results then we can see what’s happening.

Seem that is a bake problem

Yeah, I’m seeing a few 'problem areas' when I use Convert To Curves – see attached video where I have highlighted some of the areas with a green ellipse and am just converting, undoing and repeating to show the difference.

The bake distortions are a big problem, but a perspective Warp Group itself produces terrible results - circles should become ellipses but they become ovoids, and straight lines should remain straight but many become curved. Example below:

Thanks for your report, we have this logged to be improved.

Any update on this? It's been a year since this issue was reported and I still struggle with it on the iPad version of Affinity Designer 2. Any help would be great, thanks.

Welcome to the forums @Suprimoedu

It’s been given an official tag (APL-1519) so it’s known to Serif and, as mentioned by Lee D above, they have it logged for improvement.

You can find official tags directly under the thread title. If you see one then you can know that Serif have acknowledged it as being something to be looked at.

Serif don’t usually give us time-scales for changes/improvements/fixes; all we can do is wait and see. Not an ideal situation, but maybe better than getting promises which are later broken.
