I wanted to say that MXStudio crashes when trying to import a 2+ million polygones scene. It's a obj file created with Blender 3d... by the way, is there a plugin/trick to bypass Maxwell Studio and connect Blender to Maxwell engine? (any plans?)

No problems with 1M poly or less so it may be a memory issue.

I'm working a Vista64 machine with 8GB of RAM so the software should not be limited by hardware.

Sounds like a RAM issue, which is wierd for an 8GB x64 machine.

Try splitting up the model first in Blender then importing parts.

Have you exported with 'Triangulate mesh' option selected in Blender obj exporter? If MXST is trying to convert quads to triangles on import, that might be where the crash is coming from.

Hello,

First of all, sorry for this late answer. I thought I clicked on the "Notify me when reply...".

I sometimes imported successfully a 2.1M poly and sometimes not. Never more than that. Could you tell me the export settings you use in Blender?

This link shows you a screenshot of Blender OBJ export dialog. If you could tell me what do you select it would be very kind of you as you say you've been using the Blender/Maxwell combo for a long time.

Thank you, and I'll be answering more quickly next time.

Sorry too for my late reply. Here is the OBJ export dialogue from Blender 2.49.2



I've highlighted in Blue & underlined in green, the settings I use for all obj exports.

A couple of things to remember for correct scale & correct export of objs for use with MXST.

1.> In the header for each 3D viewport you have, click view, then view properties. Change the Spacing to 0.5 for each viewport. This will give you a 1mx1mx1m cube, when adding a new Mesh>Cube. When exported this will be a 1mx1mx1m cube in MXST. Any other spacing value will give incorrect scale in MXST.


2.> Make sure though you don't have a camera selected when you export.


If you do the Spacing change when you start Blender without loading a scene, you can save these settings as the default for all new scenes by pressing CTRL+U.

If you still get a crash when exporting, you'll need to export sections of your scene seperately, it may be a RAM issue.

Hope this is of help,

Tim.

Thank you!

I had found some ways to export but the scale trick will help me: I often import a huge sofa and then scale it down in Maxwell. I think I can avoid that with your trick.

Also, I sometimes have inverted normals in Maxwell when in Blender it's all ok. However, when I render, everything seems fine. Even with the export normal option I see that... sometimes. I wonder if that's just a display problem in Maxwell Studio.

Thank you for taking the time to help me!

Just to say that Maxwell 2 solves the memory problem. I just imported a 173MB obj file without any problem.

Happy to hear that Eric :)
