Question Exporting problems (AC3D to Maxwell)

Hi there

I have some serious exporting problems, when using AC3D.

When I export in 3ds format, the surfaces seem to loose smoothing, and I'm unable to reconstruct this in my render engine, Maxwell Render, it always creates a "seam", which is annoying.

Then I try exporting in obj format. This method seems to have some problems with the group settings. I have seen the other threads in this forum, but there doesn't seem to be any fair solution to these issues. I think it's unacceptable that AC3D is unable to export, let's say, two spheres into two separate objects in an obj file. I don't get why it has to combine them into groups. It really makes this export option unusable.

Then there's dxf format. This format seems to insist on flipping one or several of the axis. Does anyone have any experience with this?

In general I'm asking for help with making AC3D work smoothly with Maxwell.

In advance, big thanks...

Z.

The 3DS exporter doesn't weld the vertices. Is it possible to tell your renderer to combine them?

I have the same "problem" when importing 3ds or obj files into Bryce. On 3ds files the smoothing is gone. This is actually default settings in Bryce. I have to sett the smoothing manually. Maybe the same for maxwell?

When importing obj files Bryce merge all objects in the file into one. Really anoying, but this is because of the importer in Bryce. When importing the same file in Carrara the model has its hiarcy intact. Maybe Maxwell imports the same way as Bryce?

When importing in Maxwell, the smoothing gets lost. Maxwell is able to recalculate the smoothing, but still there's a seam left, a kind of sharply drawn shadow that stays put in the same place even when the real shadows are changed...

But I will go to the Maxwell Forum and ask there...
