Dear ARCHICAD users, I'm posting another survey - this time regarding PhotoRendering Settings and our Corona rendering panel.

As you can see in the screenshot, they are the same. We brought another unnecessary duplicity and complexity in the UI and therefore considering to remove the Corona rendering panel. By finishing this step we will unify the rendering workflow in AC and keep the standard way for setting the rendering options.
Also, we plan to bring other common AC UI elements to reorder and better group options within the palette.

We assume the PhotoRendering Settings is a very well known palette to you hence this step will be easily utilized.

As always, your feedback is more than appreciated.

We want a simple yet powerful plugin. To make it simpler, we can remove some unused features. What is your opinion on Interactive Palette?

How to handle tutorials on our forum? Do you prefer 1 thread/tutorial or you like more the collection of tutorials in one thread?

Dear ARCHICAD users!
To improve the plugin and bring it to the next level, we are kindly asking for your help.

What and why?

TLDR; We need real life scenes to replace a batch of pillars and walls with some real houses, interiors -> internal testing &research and understanding of your needs.

We [developers and architects] are not on the same wave using ARCHICAD. Our testing scenes are miles away from real-life projects you are dealing with daily.
To improve and understand your needs, we need larger, more complex projects, so we can test editor responsiveness ( Corona Proxy, etc. ), make our test renders, look at how you use materials, lights, and much more...
Please, consider uploading your projects with working links to materials, textures, libraries and everything we need for error/warning free experience.

We understand the majority of your projects are probably under NDA.
Then, some personal work, drafts, exercises will be more than welcome.

Your projects will be safe with us. They will be used strictly with our team and for our internal usage. Your project or any part of your project will be not published or sent to the 3rd parties. If you permit us to publish renders, all images will be credited properly.

Motivation booster - Corona License
To motivate you more we will provide one commercial Corona license for ARCHICAD ( once we release a commercial version ), 3DS Max or Cinema 4D.
I will draw one name from all scene submissions at the end of January 2020.  The winner will be announced in this thread and contacted by our support to handle all the details.

How to upload
Please use our service called Private uploader. We provide this tool for users to upload their scenes so our developers can debug and resolve the subject more quickly.Follow this link to read more about private uploader:


Once again, the discussion is open.
All comments are more than appreciated. Thank you!

Hello everyone!

I'd like to open the discussion about proxies. I feel there is slight misunderstanding and misuse of proxy objects usage in AC right now.
Let's sum it up.

Proxy object ( current implementation )
The current proxy is a GDL object to help to bring custom geometry into AC from a file (like .obj or .cgeo).

Corona proxy ( NOT implemented yet )
Proxies are useful for keeping smooth viewport performance while handling large amounts of high-poly objects in the scene.
This is not implemented in the Corona for AC now - you can't select the geometry and save it as a .cgeo right now.
More info:

What we want to do first, is fully implement Corona Proxy (save and load)
Making .obj importer as a separate GDL object is questionable - it's worth it and should we spend the time on this or rather on another more important functionality?

To keep the discussion rolling, will be obj. loading GDL object a useful feature? Is this a used and trusted way how to bring objects into AC? It's not better to use the objects from some well-prepared library? It's another way how to bring custom geometry into AC(plugin)?

Thanks for your feedback!
