I’m trying to understand how a simpleMeshMod works, as supposedly it lets you modify topology unlike a regular simpleMod. But when I try and delete something either nothing happens at all or just the shading on the mesh changes. Here’s what I’m doing:
plugin simpleMeshMod testModifier
name:"testModifier"
classID:#(0x5629d00e, 0x5177aa37) --use genClassID() to generate this beforehand.
category:"Test Modifier"
(
on modifyMesh do (
local curMesh = copy mesh
meshop.deleteFaces curMesh 1
mesh = curMesh
)
)I’m very sure I’m just missing a step or something really basic. Hopefully someone here can shine some light on what I’m doing wrong.
I think the problem is that the assignment you do at the end (mesh = curMesh) changes the reference of the original mesh instead of updating it (someone correct me if it’s not this, couldn’t find a source to back it up).
Anyway, what you can do is use setMesh to update the mesh with the changes you’ve made to curMesh:
on modifyMesh do (
local curMesh = copy mesh
meshop.deleteFaces curMesh 1
setMesh mesh curMesh
)or work directly with mesh:
on modifyMesh do (
meshop.deleteFaces mesh 1
)Just tested and that worked. The example in the documentation used direct assignment so I just did the same, but they were only moving points (which doesn’t make sense as it ignores the main feature of simpleMeshMod).
Thanks for the help
You are welcome
Yes, the example of the documentation threw me off too:
mesh = mesh + currentMesh --accummulate the moved value into the output meshI speculate that it what it really does is a “meshop.attach mesh currentMesh”, but I can’t be sure.
