Hi everybody and Corona Developers,

I'm observing Corona for AC from the beginning and here are some of my thoughts in general:

1. I suggest getting from Graphisoft some precise data on how AC is used - mostly for interior or exteriors?

2. For me doing interiors in AC is a tricky one - the main "core" objects are of course done in AC (walls, windows, floors, wardrobe designs, kitchens etc.) but all "soft" objects just don't work in AC. The reason for that is the performance of the Morph object which can't handle more than around 100 000 faces or makes AC work so slow that further work doesn't make any sense.
All "soft" objects I have to add in other software (like Sketchup) and render there final renders.
So, if you ask me: Do I make interiors in AC? - "Yes" and "no" at the same time! Please watch out on that when asking how AC is used.

3. For me doing exterior renders in AC also does no work for the same reason as in interiors - trees, grass and cars can't be imported to AC mainly because of speed of work.

4. Interiors can't be done with proxy files (this will not make any sense), exterior can be but requires a library of such objects.

5. Architects usually don't have a library of proxy objects.

6. Architects want to put grass, trees and cars quickly into the model without bothering about technical aspects of those objects.

7. Quality of trees is essential. Trees from Twinmotion2020.1 are still so low quality that for me its below being acceptable - Because of that I'm not going to be using this program though its free for AC users now. I can't show to a client a tree looking like toy, even though it has 2-sided leaf material shining in sun.

Conclusions:
To get Corona for AC commercially successful:
1. Corona team should consider whether it should focus on interior renders or exterior - I think exterior, because interior will probably never work in AC in a production scale. Interior renders in AC in Corona are of course valuable in early design phase but I can't imagine paining for a render engine to use it only for "test renders".
2. I think AC is mainly used for designing buildings, not interiors. Probably number of potential customers for Corona is definitely bigger in exterior renders.
3. I think Corona team need to focus on a "some-sort-of-proxy-scatter" implementation in AC with a library of objects embedded in Corona. Proxy functionality itself will not work because no one will use it since no architects has proxy files (and probably they will not buy them just because of Corona ability to get them in AC).

Think wide: Give Archicad architects ability to make final renders with all assets, otherwise Corona will be just a tool for making "marvelous quality TEST renders".

Of course, there is going to be several architects and users that will use proxy and render interiors as it is now, but I'm not speaking about 30 indivduals but much more.
Making money for Corona is probably important. Selling 30 (thirty) subscriptions will be easy, selling 30 000 of them will be a huge challenge without a rich proxy library.
Without proxy and scatter for AC Corona is no more than just a next nice render engine for almost useless renders (withut foliage).

The point is that the main problem is not in Corona but in Archicads MORPH tool itself and Corona needs fix it or find a work-around for it to get sold.

PS. Maybe Corona-Mesh-Tool with ability to have millions of poligons in AC ?

I think that an architect during his creative process necessarily needs software like Corona even if it does not serve to create high quality photorealistic renders. In a BIM software such as Archicad the focus is on the process of planning, not on the final result of a render. Corona for Archicad must serve architects to give him an instrument that does not exist to date: the perfect calculation of light. Light is the first design tool... light make great architecture, not object, morph tools or high poly trees. In my opinion, this is the added value that Corona can give to architects who have to design and use BIM software to do that.
I agree that to obtain results of the highest photorealism Archicad is not the right environment ... no BIM software would be, and this function must be left to the other software. Corona for AC can give a support that no other software can give at this moment, because Twinmotion or others that simplify the use and creation of the scenes has a very approximate (if not nil) calculation of the GI, fundamental for understanding volumes full and empty space.

Liukperry,
I totaly agree with you in most cases, I think the same. We are propably both in those 30 users I mentioned above.

Although, in my opinion, architecture is more than form, light, function etc but also context and human level  - trees are not to make renders nicer but make building sit on it's place and build up the scale. From what I have observed building renders  without surrondings are difficult to accept for clients and generally people.

Questions in my mind are:
Is Corona a tool for finding light and form or for selling projects to a client ?
Will architects buy Corona for AC if is has no scatter and proxy and ability to use them EASILY?
How to make scatter easy ?

Keep healthy !

You are right... i know this issue, and for shure Archicad is not the right enviroment... i'm only very sad about the ending of the development.. actually there aren't render engine with such result in Archicad and knowing also Corona will leave BIM software it's a pity. The only things left it's to wait for other software can make this job... so so sad, I love Corona how it works...

Thank you for this good discussion!
