Yup, file attached...
... and with the latest exporter (5.7.1) this scene became totally unusable - error is all i get:

Ah, ok... Nice to know, user friendly info always helps :)

Also found
Path Timing is partly broken. (Start & End are fine).
Random value corrupts the influenced children - their tips are joined/pulled into the world origin / coordinate center (0,0,0).
eg.


PS.
(Orange) "2 = Error" is from previously mentioned problem. (would be fine if lower value is blocked - 3 (default) as the lowest value).

Thick, 3 Steps


----------

I might have a way to make it faster again, just running tests on it now.

Nice :)

i guess 100x1000 children to render is an overkill or smthng, set to same as in preview (10x1000)
tho there are some bugs with hair generation:
- using Ribbon for Strand Shape produced and error
- lowering Render Path Steps to 2, produces an error / twice*

....
experimenting further... ;)

use scarcely (alpha stage, not really production ready), to be on the safe side rather Render Objects (also better control of the 'look') than Paths

Edit:
Basically am getting errors on the first time after changing few settings, then after, just switching some element on&off, error doesn't occur anymore... and so on.

here are Ribbons 50children250particles=125K hairs


Is there a size limit (polys/verts) per object for the exporter?

1220
Everything is possible. To be sure use power meter and measure the unit's output. It is common practice ;)

It's obvious on the ceiling lamp ;)

Check @ Helpdesk:
1. I can see jagged edges in my rendering!
2. What is highlight clamping?


1222
Could you post/share your problematic scene file?

Confirming, Displacement Values have no influence.
Reported: Issue #116

Officially will become possible with 2.79 release... recently added: Datablock ID Properties Patch ✓ In Master

Critical forward-compatibility warning: Any .blend file using new data-block custom properties saved in Blender 2.79 and beyond will crash when opened with Blender 2.78c and any previous releases (follow link above for more details).

Chaos Corona for Blender / Re: New standalone build
« on: 2017-05-06, 21:51:02 »
:)

Will this build also get updated to conform with the new release?
Interested if shading issue has been tackled? Saw that terminator shading fix is resolved. :D
I assume it's most likely part of the same monster but have missed any info on this?
Thank you

eg.

+ a Tip
SSS is VOLUME based - without other surface elements or properties (shaders, materials, fine textures, normals...) can be artistically considered & used as a homogeneous volumetric shader (ie. fog ;)

yup, this is happening also with many haven's HDRIs...

Hey,
Thanks for the file.
I see what you mean now.

Modifiers used with object A get applied to an original mesh which is then used for an instance with object B, on which modifiers do not work (are not applied/exported).

About hdr texture error, did you check for permissions or any blockers, move to another location, strange characters...?
Can't reproduce here.

Please, for every problem you stumble upon, describe steps to reproduce, your OS, HW and SW specs. Also Images & scene files are most welcome.

ie.
Blender 2.78c, CoronaSA 1.6 (jan2017), corona exporter v. 5.3.0
w7 x64 pro,

- IBL/HDR lighting works here
- multiple Arrays work
- render border works as you described: result gets offset on the import*

*/// temporal solutions:
  • save from Corona's VFB
  • find the result in your Export Path location
  • render again without border/region: previous result (from Export Path) will get temporarily imported, save before closing Corona's VFB
eg

Hi!

Wuhu & Thank you. :D

Been using "Only Modifiers" for the last couple of hours and it's working quite nice.
Will do more testing over the weekend.
