@HDMaster84 IIRC, this is a known limitation, no?

BTW, there was a bug with the tweak tool not related to this modifier. Could you test if you can move using G key?

I have no trouble selecting it with box select. Clicking to select seems to be broken. So maybe the bug is somewhere in the selection code. Maybe it tries to select the non selectable strokes, as they are first in the list of strokes?

Vyacheslav Kobozev changed title from ~~Grease pencil, envelope modifier. Can`t select points (elbt mode), when modifier enabled.~~ to Grease pencil, envelope modifier. Can`t select points (edit mode), when modifier enabled.

but I can see and move vertices, if I select em before.

True, the same, so it is bug, specific to tweak tool.

@HDMaster84 I have checked and the problem is using Envelope modifier and tweak select. If you use other modifer as Offset, you can select without problems. Check that you set the origpointers for the stroke and for the points you has created.

Following the policy of "bug in new feature = high priority", will raise priority

The reason of the bug is that new created strokes in the envelope modifier is not setting the right pointer to original stroke and points.

When using Box select, the point selected are the original stroke because Box select try to select all points in the selected area, but the Tweak tool try to select only the point that is near and as the vertex of the new stroke (generated) and the old stroke (original) are in the same position, the point selected is the corresponding to the new created stroke by envelope modifier and this is not displayed.

I'm looking at the code and trying to assign right pointers.
