Yakul - Fiat in Studio (probably)

[Yakul]

I did my first steps with VRED today and I am pretty impressed (well, that's somewhat understated ). Here are the first 2 wip versions of the Fiat. I know, Anti-Aliasing turned out too low, but these are just testrenders so who cares ...

rendertime was 154s for the first (precomputed+shadows), 333s for the second (full GI)

edit: is there any possibility to learn how to use backplates with VRED? 'Edit->Create Backplate' just gives me a white background and i really have no clue on how to change that... Btw: every time I try to change 'transp.' in the texturechunk dialog of the backplate, VRED crashes

Hello,

which kind of Imageformat do you use for the Backplate? Which resolution is the Backplate? Transparency in the texturechunk is only supported in OpenGL at the moment, so if you want to disable the Backplate switch it off in the renderoptions.

That looks good man!

hm, okay so this is strange. I just tried again and it worked fine this time o.O
I did not know that I had to hide the dome geometry in order to see the backplate. So here's my next question: How can I use the backplate and the skydome together? As I hide the skydome, any HDRI reflections pass away as well. But while the dome geometry is NOT hidden, the backplate does not appear.
In e.g.cinema 4d there's a quite useful render tag to clearify these things. How do I do it in VRED?

edit:
got another one
is it possible to use a sphere object instead of the skydome object? If so, how? I tried mapping the environment onto a sphere but there were no reflections at all at the car.

That looks good man!

Thank you!

Impressive render.I have to try this vred

Hi,

Rendering - Renderlayer
Create new Layer
Drag the skydome onto the layer
Turn Primary visibility off
Activate Layer

Of course you can do some other neat things there too

Hope this helps

thx, this helps a lot! I'm really happy that there are some of you helping us (or rather me )

edit: little workout with exidges christmas-hdri, still not satisfied with the tires and rims

[Brombaer]

your welcome ... your feedback helps us to find out where to improve the software resp documentation.

Approx one week left to go ... hope nobody burnt their cpu in the meantime :-)

need help again
I created an area light and in the aftermath wanted to delete it again, but when I did that, it turned out to be something left there (screenshot). I already looked for any kind of remaining geometry or else but did not find anything that seems related to the area light. So, how do I get rid of that ugly black thingy above the car??
(Hiding the light seem to not have any consequence...?! I would suppose that if I hid a light, it should not appear in neither the editor nor the rendering in any way?)

By the way, as you said you'd like to get feedback...
1. The 'undo'-function is pretty nasty as it actually undoes the fewest things. I would really appreciate if e.g. the tweeks I do in the material editor or any transformation of an object would be undone if intended.
2. The delete-button does not work properly in every case (see above). Some materials cannot be deleted either, but I suppose that this is due to its application to geometry.
3. Texture mapping is kind of annoying to learn. I searched for other rotation axes than the one to be found in the texture tab but there were none, I consequently spent approx. half an hour to find out how to actually spin the texture.
4. HDRI-formats are obviously only accepted if they are in the exact pixel relation of 2:1, 4:3 , etc (which is imho already quite annoying). Well, it appears that VRED does not even accept some of the edited HDRIs, that were resized/cut to the actual format, either.

nevertheless, I still have to say that VRED's a very unique and amazing program for any professional designer.

Not sure what went wrong here. What happens when you switch back from raytracing to opengl and back ? What happens when you save the file and restart/reload ?

We are working on that already.

2. The delete-button does not work properly in every case (see above). Some materials cannot be deleted either, but I suppose that this is due to its application to geometry.

You figured that out. Deleting a material that is already used does not make sense so we do not allow that. It can also happen that a material is connected to a geometry that is inside the trash can, so clearing that helps too.

3. Texture mapping is kind of annoying to learn. I searched for other rotation axes than the one to be found in the texture tab but there were none, I consequently spent approx. half an hour to find out how to actually spin the texture.

I won't argue you are terribly right. In the 4.2 series this has been completely rewritten and works like a charm (there's a nice 2d gui as well as a 3D gizmo). I have attached a preview screenshot of the upcoming texture editor

4. HDRI-formats are obviously only accepted if they are in the exact pixel relation of 2:1, 4:3 , etc (which is imho already quite annoying). Well, it appears that VRED does not even accept some of the edited HDRIs, that were resized/cut to the actual format, either.

Well, the software needs to find out if the used HDRs are long/lat or horizontal/vertical cross. What would you expect the software to do with a non matching pixel ratio ?

nevertheless, I still have to say that VRED's a very unique and amazing program for any professional designer.

Thanx, and we are still at the beginning and improving the software quite a lot. Looking forward to your next results

[Yakul]

haha here's what I just thought: I would have saved half an hour if you gave us version 4.2
I wonder why noone else seems to have any problems or so. Or am I the only one competing? Can I choose what I want to have when I win?

[Brombaer]

I understand what you mean but you may have killed us for other unexpected inconveniences since it is still work in development

Regarding your question, the winner is of course entitled to one full year of updates and support, so you won't miss that. But I would advise to use the remaining time very intensively, we have some very high profile participants

[Yakul]

I just tried again the thing with the area light and it is indeed reconstructable:
I create any kind of light in the lighteditor, positioning it on top of the car, then turn on area light, visible in reflection and some minor tweaks, scale it to 4000 and afterwards delete it. The node actually is deleted, but the light and all its attributes remain even if i close and reboot the software - the area light is still there.
Now there is obviously no possibility to delete or change it anymore... What shall i do?

/correction: apparently not all its attributes remain, in raytracing mode, it is just the reflection while every lighting seems disappeared. Open GL does not recognise any attribute of the light at all (meaning the car is black) though the white plane above the car is still visible. I conclude, it must have something to do with the "visible in reflections"-button...

[SaneG]

Please be sure, that your Light is not a child of a geometry node. When you create a light, please select the root node before. To get rid of all remaining lightattributes and the plane, go to edit --> preferences, somewhere in the rendering options under misc, you can find the checkbox show internal nodes. Enable that checkbox and you will see a new group in the scenegraph which is called lighttransforms. In that group delete the corresponding Arealight geometry. that should do the trick.
