Prompt how to make so that object it was shone
For example: it is necessary that from a window and the spaceship engine light was radiated. I am impossible to me placed Light in nozzles of engines and in windows but the necessary result have not received, learn as to reach such effects

Lights do not shine through transparent objects in Anim8or.  You can set objects to not cast shadows but this is only effective if using the Scanline renderer, if using ART renderer all objects cast shadows irrespective of the object setting.

From what you've said it sounds like putting lots of small planes will varying transparencies by your engine to make it look like it it glowing.

There are techniques to make the glowing, if that's what you need.

What methods it is particularly possible more in detail.
In drawing by red squares it is shown, where light should be radiated.
I cannot understand as it works, tried on a miscellaneous but not as it is impossible whenever possible give a lesson or detailed explanatories.
Excuse for bad English.

If you wanna create a glow in the red areas only, you should create a matte for the textures, using black as an alpha channel and white as solid. Then copy the mesh and increase it's size a bit. Anim8or can not allow to create partially reflective surfaces. Then texture the outer mesh with you texture, and the inner one add a reflection map.
The light will reflect only on the inner mesh surfaces.

You can also texture those face with a material which has a high emissive value. It will give the material a bit of a glow.

Floyd is right. That could give you almost the same effect, but unfortunately you'll be able to see the edge-line of the face with the higher emisive value when the light hits it. If that is not a problem for you, you can try it.

I wish to learn to create such effects as in this drawing can at somebody there is a corresponding lesson or stage-by-stage instructions for early thanks.

I am not really sure this is easily done in anim8or, but I can show you how I would do it knowing what I do know... Yes, it is a lot of work, but if you really want the effect, as I did with my example, you do what you have to do, knowing what you know:

1: Choose the base color that you want your engine-bright to be... and then apply it to that engine area of your ship. For the sake of discussion, make it light blue., very bright.

2: render your scene frame-by-frame in BMP or JPG.

3: Open your choice of image editor... I use GIMP, but GIMP or Photoshop or similar program...

4: Open your BMP or JPG movie frames one at a time... and select the light blue areas you want to glow...

5: Make those engine glow areas into a new layer on top of the original frame.

6: Blur your engine glow layer to the desired glow effectiveness.

7: Save your image in its original BMP or JPG format, knowing that the layers will merge back into one, this time with the glow/blur atop your original flying ship image.

8: Repeat this process for each frame.


Then, combine the edited, now-glowing frames into your intended video format (avi?).

You will have glowing engines.

I did a similar thing when I wanted a glowing effect in a space thing...

If you open the below GIF, you should see a stars in space scene that has 3 faint blue glows come together, brighten and then materialize into a triangle form of three distinct dots with a small "ship" in the middle.

The idea was to have a mass of energy materialize, coalesce and condense into the three spots of light, a ship appearing out of nowhere as if materializing from a wormhole. From this point the ship would then drift steadily toward the camera and then on to its destination.

The difference between my attached file effect and your intended effect is that my "light" starts extremely faint and large, and then shrinks in size and lessens in blur, giving the effect of the energy condensing and increasing in intensity, but then fading as it dissipates, leaving in its place the newly appeared spacecraft.

Your ship glows would blur, but as the ships become smaller, more distant, you would scale down the blur to match the idea of their becoming further away.

Does that make sense? Or would you like me to take time to make a sort of pictorial tutorial?

In this tutorial are some tricks to achieve glows and lighteffects: http://anim8or.com/tutorials/from_users/lighting_tutorial/Lighting.htm

Always gotta go and show some easier way to do things, don't ya?  ;-)  Just takes all the fun out of it...

And without Photoshop, it imagine, and if hundreds or thousand it is very inconvenient, and means Anim8or probably to realise it.
If it is possible, I ask detailed instructions.
