Short description of error

It seems like there are a couple of issues for text/curve objects with modifiers in 2.8:

1. deforming modifiers

  • I see a TODO comment in `MOD_get_mesh_eval(): /* TODO(sybren): get evaluated mesh from depsgraph once that's properly generated for curves. */

    • @dr.sybren A. Stüvel (sybren) : do you know the status of this?
  • Then for following modifiers:

    • we are asserting BLI_assert(mesh_src->totvert == numVerts);
    • if I remove the assert, the modifiers are actually working seemingly fine for e.g. text objects
    • @mont29: do you know the status of this (are these neccessary only for mesh objects)?
      • Cast
      • Curve
      • Shrinkwrap
      • Smooth
      • Warp

2. generative modifiers on curves not working (basically all of them):

  • Array
  • Bevel (wasnt even there in 2.79)
    • What is the point here? Bevel of surfaces???
  • Build
  • Decimate
  • Mirror
  • Remesh (had bad results in 2.79, but not working at all in 2.8)
  • Screw
  • Solidify
  • I havent looked into the cause of this yet...
  • maybe @mont29 would know right away?

Exact steps for others to reproduce the error

1. e.g. Cast modifier asserts

Add text object
Add cast modifier -> assert

2. e.g. Solidify modifier doesn't increase thickness of text objects in 2.8

Add text object
Add solidify modifier
increase thickness -> text remains flat

We have a similar (curve/modifier related) report in #57958.

Taking a step back, it seems like there are a couple of issues (for text/curve objects):

1. deforming modifiers

  • I see a TODO comment in `MOD_get_mesh_eval(): / TODO(sybren): get evaluated mesh from depsgraph once that's properly generated for curves. **/

  • Then for Cast, Curve, Displace, Shrinkwrap, Smooth, Warp:

    • we are asserting BLI_assert(mesh_src->totvert == numVerts);
    • if I remove the assert, the modifiers are actually working seemingly fine for e.g. text objects
    • @mont29: do you know the status of this (are these neccessary only for mesh objects)?

@PeterKrauspe: altered the task description (as it turned out to be a much broader "issue"), hope that's OK.
(This way we can also merge in #57958)

@mont29: before this gets forgotten in the abyss: could you take care of this / have a look (thx in advance - not sure who would be responsible otherwise?)?

reg. Bevel on Curves: seems weird, but 75149b429f... [no idea how to use it, or what it is good for... can check tomorrow]

Generative issue is actually a drawing issue (see #58107).

Deforming modifiers shall all now work OK I think, so we can close that one, yeah!

I've fixed modifier display for curves.

bug_curve_solidify.blend

Seems like all Deforming modifiers are working correctly except the solidify modifier.

Solidify is not a deforming modifier, it’s a generative one, would rather have another report for that, that one already had way too many different issues in it!

Forgive the necro post, but I wanted to check something before creating a new bug report about it, as all searches seem to lead to this report...

Putting the Array modifier on a Curve and using the 'Object Offset' (without Relative or Constant Offset) causes the arrayed Curve objects to render incorrectly in Cycles (it's correct in EEVEE), as if the wrong transform location/rotation are being used for the offset source object, making them splay/scatter all over the place. The selection outline shows them in the correct place though. It works fine in 2.79 as well.

Is this behaviour because of the above issues mentioned, or something else? Is it worth creating a bug report for it, or will it be fixed later? Cheers.

@browneggz Yes, please open a new report, if its working in eevee but not in Cycles it's likely something with cycles itself, and/or our rendering pipeline/API…
