Quick preview rendering

[sreinger]

Hello first.
I try to render a fast preview and want only white objekts. I tried the "Info Kernel" -> Type: Ambient Occ.
I reduced the subdivision (read it in this forum) on level 1. So i have 11 million triangles.
I take the same options from my live viewer to the render options. On live viewer octane rendering big screen in only 1 second !!
Final render takes 7 second per frame for a little picture
too long for me, i want only very very fast raw preview.

whats wrong here ?

Post render log outputs from Console window, press shift+F10 to open it

aoktar, nice to hear you.

Not easy this time, my Cinema crash often because this scene is too large. It freezed a lot.
Before i start render, i delete all meterials.

very interesting, it is 26million polygons and in previewer only 14mio. I dont know why. when i deactivate all subdivisions, i have 11,8mio in previewer and 18mio in renderer.

[aoktar]

Subdivisions have different parameters for editor and render, because of this have different triangles amount. Also some other objects can have the same behavior.

Also what you see in LV times is just render time without scene preparation and prepare to the renderer.

[sreinger]

Ok, but the scene preparation is only the first image, here it is 85 sec.
not problem.
but following images need 6 sec. to render but only 1 sec. in LV.
Irradiance mode not faster. Do you mean, that 6 sec. is minimum to render an image? Octane not faster ?

When i render my scene without octane, normal Cinema Renderer, an image needs only 1 sec. to render. Without light, texture and antialaising.
i think in this case, the cinema renderer is better for fast preview.

But i want to understand how it is possible to make ultra fast pre rendering with octane in irradiance or info kernel mode.
Yes, i have all subdivisions on level 2 ! editor and renderer

Seems like you didn't try a different scene for testing. Of course you can render at 1 sec, it depends to many factors. How heavy for preparations, and updated things between frames. It will help you that spending some attention to where it's busy mostly. Try to optimize these parts.
