Hi

Help appreciated with this

I am have poser 2010 , windows 7, amateur user of poser

I am doing a bedroom scene where a person is reading a smartphone on the bed.

The room lighting is low so I need the smartphone to shine in a persons face, also to be able to read a message on the smartphone with an image map.

Any suggestions appreciated.

Thanks

Inside Materials Room, connect tablet screen image texture file to Alternate Diffuse node.  Render to see effect.

No,
Put the screen texture in the ambient_color node and set ambient_value to 1 or higher.
Render with IDL enabled.

Thanks for your response, unfortunately I tried both methods and the smartphone stayed black.

I attach a snapshot of the material for the smart phone, the texture manager is for 1 of the image maps.

Could you please review and advise, as mentioned I am looking for the smartphone to emit light and be able to read the screen if possible.

Thanks

Re screen shot: try attaching the image file to the Specular Colour item, not the Specular Value.

Set ambient_color to WHITE.

Then attach the DIFFUSE texture into ambient_color node
Set ambient value to 1 or higher.

Throw the specular texture out of the door, you do not need it.

Set Ambient_Value to 1000 and your smartphone will light up the whole room. LOL.

Tonight, I"ll attach a similar shot of a PC screen, its the same procedure.
You ONLY need the to use the Diffuse texture, nothing more.

@raven - great one !

The problem with devices like smartphones, tablets Tv's, and monitors is that the illumination output is unrealistic using the ambient channel, images become washed out.  Recommend using a spotlight to simulate that type of lighting.

Many thanks for the feedback, appreciated.

The possible results look great so I am keen to learn the technique.

I do not know which is the diffuse or spectacular texture so I have only connected image map No.1

Please see screenshot attached, still no luck as there is no light emitted.

I am in manual render mode with indirect lighting enabled.

Can anyone see what I am doing wrong.

Thanks in advance

From your screenshot it looks like you've applied the image to the 'speaker' material, try it on the screen instead.

Correct, you need to put the texture on the screen.
And as you render with IDL, and ambient only becomes visible at render time, you will not see any light in the preview.

I'm trying the same trick on an Ipad like prop and having trouble with getting the screen texture to be legible when turning up the ambient.

Left PC has the texture in Diffuse_color
Right PC has the same texture in Ambient_Color
=> See how it lights up the keyboard?

For best result, set texture filtering to Crisp

Raven, I know it might be a quick and dirty render but the illumination isn't quite right. I can't see any on the smaller fingers close to the screen, only the index finger and face. I'm just starting to dabble with IDL so I'm interested to know if it's the IDl setting or a limit of Posers IDL handling

It has nothing to do with IDL, everything to do with realistic rendering.  The ambient channel approach is adequate for large surface areas where you would expect a substantial amount of light to be shed.  However, smaller devices, TV's and monitors do not emit such an intensity as I stated earlier in the post and was ignored.  IIRC, Bagginsbill made such a statement in a separate thread and suggested supplementing light emission with spot lighting using material ambient at a low intensity to avoid washing out the image and casting an unrealistic glow.

Just for fun I also rendered it in PoserPro2012 after EZSkinning the figure and using SSS in the render to compare the difference available in PPro2012 to PPro2010. Click it to see it a bit bigger.
