Point Cloud Plugin

[phoboz]

Hi - thanks for the quick reply.



- It works fine in the editor view.
- It fails in PIE and separate window.
- The cloud is statically loaded.
- No custom material - I'm using "point, unlit, solid colour".
- No changes to default setting that I can think of.
- I've got about six or seven other plugins enabled.
- I have not tried it in a fresh project.

Based on what you said I will try the point-cloud plugin in a new project with all other plugins disabled and let you know what happens.

Is the crash happening on 0.4? You mentioned solid color render mode, which was removed in 0.4

[Derek Hunter]

The crash is on 0.4.

You are right. I did say "solid colour render mode" but thinking about it now I'm 99% certain I was using the new render mode.

I will try on a new project today.

This from a customer who is using 0.3: "The Point Cloud is fantastic!"

Happy to hear that

Derek Hunter Are you still experiencing crashes?

[phoboz]

Point Cloud Plugin v0.4.2
Release Notes

Fixes

• Fixed an issue with point clouds not loading at startup sometimes.
• Changing Render Method at runtime should be much more robust now.

Hey,

I have a feature request: the plugin currently only imports the RGB channels for the vertex colours. Would it be possible to get the 4th channel too (alpha)?

It would be really useful to be able to have a fourth data channel in there, because it could be used to drive certain effects in the material. Just a thought.

Thanks!

Hi and thanks for the feedback!

I'm experimenting with something that might end up using the alpha channel for other purpose but if not, then It's certainly possible and I will add it to the next release

[localstarlight]

Awesome!

Or perhaps there is an alternative / better way to get different amounts of rotation for each point that you can think of?

[phoboz]

Depends on what you're trying to achieve. How many axes of rotation? Random or specific rotation?
For random you can use things like world position / color component etc.

Ah, you're right, I can actually achieve what I want by just using/combining the RGB colour channels - oops! Thanks!

No problem Glad I could help.

Hey guys just out of curiosity, what would you use to export a point cloud that has information stored in an alpha channel? This is in regard to localstarlight earlier question for phoboz.

I'm producing my point clouds with Houdini, so it's just a case of adding an alpha channel manually with whatever data I want. If you wanted to add an alpha channel to a point cloud you had in CSV, that would be pretty easy to do in Houdini too.

Any idea what's going on here?

If I remove the point cloud plugin (and all point clouds from the project), I don't get this error and the project packages fine.

I'll have a look tonight and see what causes it.
You mentioned it only happening occasionally - as in, the same project will sometimes build without problems or that only some projects suffer from it?

Some control questions:
- Are you using the v0.4.2?
- Is the issue reproducible in fresh, empty project with just the PC in question?
- Are you using binary version of 4.18?
- Is it a code or content-only project?

Thanks for the feedback
