Artur - regarding your white trees. This is most likely occurring because the texturemap for the tree is inside an ArchiCAD library archive (icf file). To get around this, extract the archive and use the extract as your library. I am certain you know how to do this, but on this 1% chance you don;t....

1) File->Libraries and Objects->Extract a Container. Select whichever your current library is (which contain the tree texturemap) - most likely "C:\Program Files\GRAPHISOFT\ArchiCAD 16\ArchiCAD Library 16\ArchiCAD Library 16.lcf". Extract into you My Document\ArchiCAD 16 Library folder (or similar)
2) File->Libraries and Objects->Library Manager. Click the library you just extracted in 1 and delete it (X button). Then "Add" and select the folder to extracted to above (it should then display "Object Library 16" and "Zones 16" under "Linked Libraries".
3) In the plugin, select "Re-convert from ArchiCAD" for any GDL materials which had texturemaps inside the lcf library.

The above is .pln file specific - so you will need to do the above on a blank document and save as a template if you want it always applied by default.

I need to add the above info to the Manual and FAQ at some point.

Just at starting opening the project the critical error "Too many materials. This plugin has capacity for scenes with up to 1000 materials." comes up. Not only once but perhaps about 200 times.
Then at initialising Octane the same game again And at opening the viewport again 200 times - an "OK-to-all" button would be nice !

This is a function of all GDL objects now having unique materials. So if you have 100 trees in your scene - each of those 100 trees will have their own material name (assuming internal GDL materials and not references to general ArchiCAD materials). If each tree has 2 internal materials, that 200 materials. and you can only edit one material at a time with the plugin.

So, for GDL objects, they can either all share the same material names (so "GDL_black" for a tree is the same Octane material as "GDL_black" for a tree). This is the way it was in 1.11.

OR, they can all be unique (so "GDL_bark" for one tree instance will be different from "GDL_bark" for another instance of that same tree object). This is how it currently is with 1.13.

Unfortunately there is no in-between.

To get around the "Too many materials" message, I will increase the number of materials from 1000 to 10000. And if you ever get the "Too many materials" message, subsequent occurences of the warning will be suppressed.

Hi Paul,

for smoothing I am for option 4)
@ acc24ex: I would be really interested in seeing an example...I haven't had any problems up to now with low-polys.

My white trees...their library isn't a lcf-file (?!). Apart from that I know how to extrac them (I struggle with Archicad already since 1998 )
Two days ago I extracted my Archicad16 libraries to be sure Octane is not missing something out there.
The textures I actually use are in an other folders.

I need to add the above info to the Manual and FAQ at some point.

Good idea, the "standard-Archicad-user" is probably using the materials that come up with it, so the textures are in the LCF.

You would'nt believe...i started writing something similar - but just with cars Unfortunately my browser crashed, so it's lost...

However, I think this could be solvable;
If there's a definition like >DEFINE MATERIAL "BARK" 4,0.8,0.0,0.0"< in GDL and the object finally uses it, then - of course - this shoul be unique and the stuff get its ID.
But later in the script might be the option to let the user pick up a Material (in the parameters of the object) from the Archicad-list. In that case the ID is not needed.
A little queue: open obejct -> what materials are you using ? -> IF material in Archicad-material-list -> THEN no ID -> IF material not in Archicad-material-list -> THEN add ID
I'll upload you an object where such selections can be made (Link like always; Car for GDL-material-check.pla)
I'm a greenhorn according in programming, so sorry if I made a mistake with my thinking !
The lower the material quantity is, the better is it, isn't it ? 10.000 shuold be enough anyway

Shit, it's 5:30am through - Good night

I think there is an idea in there. I will await your upload. For the moment I would like to fix all the problems you are having. Then when that is done we can talk enhancement like this

I have updated the installers in the first msg of this thread.

1.13a3
- Fixed "unique" GDL number not correctly matching some GDL materials
- Smoothing is now ON by default when converting ArchiCAD materials to Octane materials
- If you get a "Too many materials found whilst loading geometry for element [XX]" message, subsequent similar messages will be supressed for that scene load
- Increased the maximum number of scene materials from 1000 to 10000, and suppressed additional warnings if you go over this limit
- Fixed issue where photorendering was not working
- Fixed issue where the "fov" of the Viewport was left in an incorrect state after photorendering
- Fixed issue where the "fov" was wrong for photorendering
- Fixed issue where photorendering would crash if "Scene Refresh on View Change" was enabled in the configuration

Pls re-download from the original links at the top of this thread.

Would you like fake_shadows ENABLED by default when converting specular materials?

I neglected to fix the missing specular camera - will do so on the next update.

Personally I did not experiment with fake_shadows to give a founded answer.
If you like you may explain a little about it?

Hi Paul,
I get this message when trying to change the material node.
Am I doing something wrong or is something going wrong?
