2.8 Hurdles and Roadblocks

@dostovel Hey Omar, nowadays the input of the Displacement is a Vector input (purple colour). You need to use a Vector > Displacement node like so:

with:

and without:

@dostovel Well, I did follow an emergency treatment course;)

Ok guys , heres another one I’ve ran into :

K is the knife tool , but SHIFT K was another type of knife in the older iterations of Blender that would cut through all the geometry on the plane you were looking along. SHIFT K in 2.8 now does nothing , but I notice on the T panel , in the knifes sub-section , that there is a “bisect” tool. 

Is this designed to work the same  as the old SHIFT K operator? And if so then can somebody explain how it works because I have played about with it and have got nowhere, 

I am currently taking Kent’s new treasure chest course to refresh myself on the full Blender workflow and to get to grips with 2.8 and that SHIFT K tool would have been really handy for part of it that I was modelling. 

Thanks guys 🙂 

@frikkr I have never used the Bisect Tool, but I’ve tried it and it’s fun. It cuts through the mesh but only along a straight plane.

To get it to work you must Select the mesh (all the vertices!) then just left- click and drag a line (both in right- and left-click select). Can be translated and rotated after the cut has been made.

Sun Light

A sun light provides light of constant intensity emitted in a single direction from infinitely far away. A sun light can be very handy for a uniform clear daylight open-space illumination. In the 3D View, the Sun light is represented by an encircled black dot with rays emitting from it, plus a dashed line indicating the direction of the light.

Strength

Strength of the lights in Watts per square meter.

Angle

The size of the sun light according to its angular diameter as seen from earth.

@smurfmier1985 So we can’t control the softness or hardness of the shadow. Well that sucks, Blender is useless now, I’m gonna go get a 3DS Max license.

@dostovel A little addition to what Miranda said:

you can control the softness of the shadow by changing the angle.

Here are some beautiful renders to show that:

Sun Light with an angle of 1:

And with an angle of 11:

This doesn’t seem to work in EEVEE, so that’s why Miranda didn’t know, probably;)

@smurfmier1985 Cool, I didn’t know that about the radius!

However, it doesn’t seem to affect the harshness of the shadow in any way…
