As many of you know, it's a simple method of making portable studio.

I made it for korean maxwell newbie, but I thought it's a useful to someone who want to make a studio.

For my poor english, I just post some pictures in here.





I started the top-left on the first photo. It's a actual portable studio for sale.

So I made it to mxi texture.

Than I applied it to cover object and rendered.


quick render tests



and another studio

nice work mate

[sandykoufax]

Thanks, Dave.

[Mihai]

Nice!

I'm not sure if there will be an issue if the emitter intersects with the backdrop. Will surely not produce render errors, but might increase render time.

[sandykoufax]

Yes, Miha.

I'm not sure what will be happen in case of intersection, but see the below result.

I tested 2min quick test twice and result of benchmark is ;

intersection : 71.01 / 70.86
not intersection : 66.19 / 65.86

I don't know why.

very nice setup Sandy !!

Clean and efficient!

[Tim Ellis]

Great methods Sandy. Thanks for sharing.

Tim.

[sandykoufax]

Thank you good friends.

Now I can't doing this method with MR 1.5.

When I load a mxi file for emitter, below error message displayed.

".... contains render data. MXI used as texture must be generated from image/hdr "

now should I use HDR for mxi ?

[zoppo]

strange.
but anyway you can save the rendered image now as hdr and then transform it into an hdr. at least a work around ...

I've updated this tutorial for the maxwell 1.6

-----------------------------------
1. Soft light box making



Now we start with the top-left photo. It's a actual portable studio for sale.

So we make it with maxwell.

1) Create about 150cmx40cm plane and apply white fabric material.

2) Create two cylinder for emitter and turn to poly and delete useless faces for minimum total polygons.




3) In the cylinder object properties, uncheck the 'Visible to Camera' option.

4) Apply an emitter material (about 400watt) and turn off the BSDF layer.

5) Create camera and render it




6) When it reached suitable sampling level, stop render and save images to 'emitter.hdr'

Of course, you can adjust iso or shutter during rendering.




7) Launch 'photoshop' and open 'emitter.hdr' and reduce brightness and turn to 8bit/channel mode and save it to 'emitter.jpg'

(this jpg image is used for only uv check )



2. Create portable studio




1) Create studio bottom plane and apply maxwell material which you want.




2) Create an arc with spline and extrude and normal.

Apply the unwrap modifier and click 'edit' button.




3) In face selection mode, select all faces and apply 'mapping > unfold mapping' in the menu. (picutre 1,2)

Stretch all faces to fit to bold rectangle (picture 3,4)




4) Create new material and assign 'emitter.jpg' to Reflectance 0

Enable 'show maps in viewport' and you can see the mapped image.

And now turn off the BSDF layer and turn on the Emitter layer

Select 'MXI/HDR texture' and assign 'emitter.hdr'




5) Place the object you want.




6) Select the environment setting to 'None'

And if you wanna more reflection, you can use 'Image based Environment' (reflection and refraction) with HDRI like below



All setup is done.

Now hit the render.



quick render tests

download all scene file included max, mxs, hdr, jpg
(3dsMax2008, Maxwell 1.6 used)


And you can make other type softdome or diffusing box like below.

ps) you can use photoshop for the fake hdr emitter image.

1) create new image and turn to 32bit/channel mode
2) fill bright grey to image
3) using lasso tool, select circle area
4) fill white color to circles
5) apply gausian blur
6) save it to hdri

of course it's fake but render result is similar.

who care?

[Hervé]

who cares... hehe.. you Sandy... great tut.. as always... hehe

[sandykoufax]

Thank you, Sir.
