Hello,

I'm trying to export a model from Shark FX 5.5 to Hypershot. In order to maintain the separation of the individual parts I've colored them differently since, as I understand it, Hypershot will translate the different colors to designate separate parts.

This has been only partially successful. I still have incorrect pieces from random parts of the model somehow linked as the same part in Hypershot which then incorrectly applies the same material to both when I apply materials.

Any help would be greatly appreciated. Do I need to first apply different materials in SharkFX to establish texture coordinates?

Help please!

Thanks Nick. I couldn't find a solution, so I tried translating to Hypershot via STEP, which seems to work correctly. If I find any other information, I'll post it here.

Mike, I just posted a question on the Import/Export forum about this. I didn't specify the reason, but here's why:

I've been trying to export to Keyshot to render, and have found that giving each material it's own separate color does nothing. I've only tried exporting as OBJ, 3DS and DXF. Been unsuccessful in all three.

So, I saved the file as an OBJ and opened it in Rhino. Changed each object/material to its own unique layer - at this point all objects were the same color. When saved as a Rhino file, Keyshot recognized each layer as the individual objects and only then was I able to apply the correct material to the correct geometry. Worked wonders from that point on.

I tried the layer thing in Shark 7 but to no avail. It doesn't seem to recognize individual layers from a shark file no matter what of those three file formats I export as. Perhaps there are other settings that I haven't tried messing with...?

The bottom line is that I really don't want to have to open Rhino to get Keyshot to properly recognize my geometry.

Good to hear that misterrogers.

I've been playing a bit more with setting pen colors in Shark, and then exporting .obj to Shot, where I specify "group by material". It's working pretty good.

Does Keyshot have a "group by material" choice? and are you using 1.9 or 2?

Mike...

I'm using v2.1. I haven't located an option "group by material" but during import the menu does offer a "retain materials" option. Keyshot is terrific!

Thanks for the info. What's does the Advanced Sewing Settings do that I see in the screenshot?

I've just bought OctaneRender and I have the same problem here too, so it seems like there could be something slightly amiss with ViaCAD's export as it's the common denominator.

The work around that I'm using is to import the .obj file into blender and immediately export it back out. I'm applying different colours to each part in ViaCAD, so that information is being picked up by Blender.

Any chance of this being checked out by Tim and Co, as Wavefront .obj files are one of the few options for getting models into rendering software and it needs to be a smooth process?

As an aside from the above. Octane is looking very good to me, with some cracking renders, that to my eye, are the equal of anything else - they really can be photorealistic and with the realtime display update, you're not waiting around for long either. Excellent value for 99 euros :)

I've been playing about with AccuTrans3D and it appears to make the necessary repairs to Wavefront obj files that are produced by ViaCAD, to allow each object, or face of an object, to have its own material within my rendering application.

So for anyone facing the same problem, simply import your obj file into AccuTrans3D (with different colours applied to each object within ViaCAD to represent different materials) and simply export it back out without doing anything else and AccuTrans3D will have sorted out the missing/incorrect data in the file.

A fix in ViaCAD would be nice though, please.

I've never used any of the Shots... or any other renderer come to that, apart from the one built into ViaCAD Pro7, so I have virtually zero experience in this field.

As for Octane, well, I wouldn't say it's been easy for me to get started, but then this whole rendering thing is a bit of an art, bearing in mind that you're playing with the physics of light and all that.
