neon glow like this

[chow choppe]

 

how to make the glow similar to SWENSEn'S text

its different from normal vray light materials and has a gradation to it

please help

V Ray light - gradient ramp or Fall off in the opacity slot ? RK

[chow choppe]

can try that out

but do i need to map every alphabet separately?

as the glow is maximum at centre of each alphabet and is darker at the edges

The way you could try to do it is block out the chunky text. apply a translucent material to the front.

Create spline profile text to fit inside.

Apply the vray light material to light from spline (you can do that in vray cant you?). Or you could sweep a circle along the spline and just add a normal vray light material to resulting geometry.

 

If that doesn't quite handle the falloff properly you could apply a grayscale map in the translucency to handle the effect with white in the center and darker gray/black at the edges.

jup - every alphabet seperately - RK

Do it in Photoshop either in post or make a custom map for the text and use it as the map for a VRay Light Material.

You can use VrayLightMtl .

1.Make a "Text".

2.Rendering/material editor/material browser....

select VrayLightMtl.

+1 from me.... that's exactly how I'd handle it. Then it's just a play of the color of your front face with the translucent material, versus the color and intensity in your interior light source.

BTW.... might not necessarily be neon.... it's just a backlit sign.....

still use vraylight MLT

[abmitalia]

Go for Brian's one - , with vray light mtl only its possible but you get crazy - tried it out, -------good solution Brian! RK

id use 2 vray light materials in a blend using vray dirt to mask between the 2

then you can also have the shiny clearcoat on the material as well.

For the quickest acceptable solution, I would do the following.

 

Create a Vray 2 sided material.

Front material is your red perspex, which is a normal Vray material.

Back material, make a Vray light material (make sure "emit on back side" is ON, in the map slot of the light material, put Vray Dirt. Make the occluded colour very dark red, almost black, and the unoccluded colour just normal red.

Now go back to the base of the 2 sided material parameters, now play with the translucency colour. The results will be immediately visible in the material editor.

In the Vray dirt map, you will have to push up the occlusion radius quite dramaticly to see results.

 

For preview purposes, change the preview ball in the material editor to a cylinder or cube rather, because occlusion will not show on the ball as it has no corners.

This is just a basic description, obviously you gotta make tweaks to get it looking the way you want it.
