A couple of notes to help people use the new instance options:

Instance Range - This allows you to set a maximum value, let's say in an example you set it to 10. If you have ten instances then each instance will return a value which increases smoothly from 0 to 1 in 1/10 increments, so if you are using this to drive a simple gradient, it will smoothly transition from the first color to the second color across each instance. If you have more instances, let's say 20, then it will cycle so you will get two complete cycles. If you have 20 instances and set the max value to 5, you will have 4 complete cycles and so on. if you have 10 instances and set the max value to 20, you will only get colors based on values between 0 and 0.5.

Instance Color - This kind of works in a similar manner, but it uses an input image map and will use the values in the image map one pixel at a time. So you will probably need to produce a specific lo-res image map to do what you want to do with this. I am guessing that this will work most logically with a rectangular array of objects with an input image map with matching dimensions, but you don't necessarily have to limit it to that. Again if you have more objects than there are pixels in the image, they will start again and cycle around.

Of course you still have the Random Color option which returns a random value per instance.

I hope these notes are helpful.

New update posted to this thread. This is a stable version of Octane for Carrara 3.07 please report any issues found with this release here.

New update posted to this thread. This is my initial release for 3.08 feature support. OSL shaders are still in the works but toon and metal materials are working.

Note that Toon Materials only work with Toon Lights. You can add a Toon Point Light by

• Add a Carrara Bulb light
• Switch to the Effect Tab
• Enable the Octane Bulb Light
• Set the emitter type to 'Toon'.

To add a Toon Directional light:

• Add a Carrara Distant light.
• Switch to the Effect Tab
• Enable the Octane Directional Light
• You can change the direction of the light using the Distant Light widget in the Assembly room.

Happy Rendering

Hi Simon,
Not a huge problem, but thought you might want to know, or let me know if it is just my machine:

Colors seem to have gone off in the Carrara LDB.
Blues for coppers, corten, gold, etc.

Octane DB via the Local Tab shows correctly.

Please see attached.

Thanks,
Rick

A new update has been posted to this thread.

Added OSL Texture and OSL Projection script support.

To load an OSL script:
1) Create an OSL Texture or OSL Projection shader.
2) Click the Load button and select the OSL file you want to load.
3) Click 'Compile' to validate the script and get a list of inputs that you need to add to the shader.
4) Click 'Generate Inputs' to generate the needed inputs.
!!! WARNING !!!
After generating inputs you MUST close (and then reopen) the shader editor window. If you do not then Carrara will likely crash.

Happy Rendering

Hi Simon,
I used the Batch Queue last night. Worked like a charm! If I haven't thanked you for it yet ..........Thank you for that. It will be a life saver.
Best,
Rick

Please help. Can't get the OctaneRender for Carrara (stable OR test) to render color/materials. I believe I'm using the defaults (use the Animated Ocean example). Here's the PhotoRealistic vs OctaneRender. (somehow the TEST version was a bit lighter - stable is pictured). [same thing happens with any of the default scenes, shapes only]

Photorealistic:


OctaneRender:

That's very odd - there is a setting for saturation in the Render Target panel but it is set at 1 by default and I can't imagine you have set it to 0 accidentally. So I can't think why this happening. I hope Sighman will be able to sort you out.

Are also you experiencing this with very basic Octane materials?

Sorry, I can't find the 'Animated Ocean' example. Can you point me in the right direction or post a sample scene...
